U.S. Secretary of State Marco Rubio on Saturday blasted the idea of a "world without borders," warning European leaders that unchecked mass migration is destabilizing Western civilization and eroding national sovereignty.

Speaking at the annual Munich Security Conference, Rubio criticized the post-Cold War belief that the world had reached the "end of history" — an era in which liberal democracy would spread, and national borders would fade — calling it a "dangerous delusion."

"This was a foolish idea that ignored both human nature, and it ignored the lessons of over 5000 years of recorded human history, and it has cost us dearly," Rubio said.

Rubio stressed that border security is not rooted in exclusion, but in responsibility.

"We must also gain control of our national borders, controlling who and how many people enter our countries," he said. "This is not an expression of xenophobia. It is not hate. It is a fundamental act of national sovereignty."

Failing to do so, Rubio warned, is "not just an abdication of one of our most basic duties owed to our people — it is an urgent threat to the fabric of our societies and the survival of our civilization itself."

The U.S. top diplomat added that lax enforcement threatens "the cohesion of our societies, the continuity of our culture, and the future of our people."

Rubio’s remarks come amid mounting political tensions in both Europe and the U.S. over migration, asylum policy and border security.

Outlining America’s direction under President Donald Trump, Rubio said the U.S. seeks to rebuild its alliance with Europe on stronger footing.

"We want allies who can defend themselves so that no adversary will ever be tempted to test our collective strength," he said. "This is why we do not want our allies to be shackled by guilt and shame. We want allies who are proud of their culture and of their heritage, who understand that we are heirs to the same great and noble civilization, and who, together with us, are willing and able to defend it."

"We in America have no interest in being polite and orderly caretakers of the West's managed decline," Rubio said. "We do not seek to separate, but to revitalize an old friendship and renew the greatest civilization in human history."

RUBIO WARNS NATO ALLIES US IS 'NOT SIMPLY FOCUSED ON EUROPE,' DOESN'T HAVE UNLIMITED RESOURCES

The secretary said the U.S. seeks an alliance "ready to defend our people, to safeguard our interests, and to preserve the freedom of action that allows us to shape our own destiny, not one that exists to operate a global welfare state and atone for the purported sins of past generations."

Rubio reminded attendees that America’s ties to Europe stretch back centuries, saying the U.S. will remain permanently linked to the continent.

"What we have inherited together is something that is unique and distinctive and irreplaceable," Rubio said. "Acting together in this way, we will not just help recover a sane foreign policy, it will restore to us a clear sense of ourselves. It will restore a place in the world, and in so doing, it will rebuke and deter the forces of civilizational erasure that today menace both America and Europe alike."

Marco Rubio could not be immediately reached by Fox News Digital for comment.

FIRST ON FOX: Eduardo Bolsonaro, son of the currently incarcerated former Brazilian President Jair Bolsonaro, is a man on an unofficial diplomatic mission in the United States. His objective is to free his father, who is currently serving a 27-year sentence at the Federal Police headquarters in the nation's capital.

Convicted on charges of plotting a coup d'état, leading an armed criminal organization and attempting to violently abolish the democratic rule of law, Jair Bolsonaro remains a popular yet controversial figure in Brazil, and who still commands a devoted following nationwide, especially in the southern strongholds of Rio de Janeiro and São Paulo.

Eduardo Bolsonaro has pursued a "maximum pressure campaign" against the current Brazilian regime on behalf of his father, lobbying the Trump administration for sanctions against the country, and for Magnitsky sanctions against the head of the Brazilian Supreme Court Alexandre de Moraes.

RUBIO WARNS BRAZIL OF US RESPONSE AFTER BOLSONARO'S CONVICTION FOR PLOTTING A COUP

In 2022, Luiz Inacio Lula da Silva narrowly defeated incumbent Bolsonaro in the closest election since Brazil's 1985 return to democracy. This followed Lula's dramatic release from prison by the Brazilian Supreme Court in 2019, where he was serving a sentence for corruption.

While many expected São Paulo Governor Tarcisio de Freitas to run in 2026, he declined, clearing the way for the former president's other son, Sen. Flavio Bolsonaro, who declared his candidacy last December.

Speaking to Fox News Digital at the Hispanic Prosperity Gala at Mar-a-Lago Eduardo Bolsonaro discussed the present situation.

"A lot of polls are showing that my brother, Senator Flavio (Bolsonaro), is tied and some of them he's a little bit ahead… Flavio just launched, just announced that he is going to run. It was a big decision that Jair Bolsonaro took, recognizing that it would be impossible for him to run in the October election, for sure, because he's in jail now. Unfairly, but he is. This is a fact."

Eduardo Bolsonaro believes the nation's economic and security issues will propel his brother to victory.

"The strategy of Flavio is to show how bad the Lula administration is, mainly in economy and also in security. These are areas where Flavio is doing very well… everybody's fed up with Lula supporting Hamas, increasing criminality, and not doing a great job in the economic area. So, Flavio, for sure his focus is going to be on the economy and security to defeat Lula."

While Flavio Bolsonaro and Lula are clearly the top two contenders, several other right-wing and center-right candidates have entered the race, including Minas Gerais Governor Romeu Zema, Parana Governor Ratinho Junior and Goias Governor Ronaldo Caiado. 

Eduardo Bolsonaro dismisses concerns that the current electoral scenario could split the vote and lead to a first-round electoral victory for Lula.

"It doesn't matter who is going to the second round; against Lula, everybody will be together. Because we all know that the worst that can happen to the country is the re-election of Lula da Silva. So these polls that are trying to say that Lula… can win in the first round, if the right-wing movement splits the votes between these candidates, this is a lie. For sure, this is not going to happen."

"And for sure, it's very good that we have more candidates on the right-wing… Why? Because they will all criticize Lula da Silva. So, even Flavio is publicly saying that it would be a good thing to do to support more and more candidates for the right… against Lula."

While former president Bolsonaro is incarcerated, his movement enjoys strong support in the Brazilian Congress, which recently passed legislation that would dramatically cut his prison sentence. 

However, Lula vetoed the legislation in January, which means that Congress may now seek to override that veto. Additionally, the Supreme Court, which is unfavorably disposed to Bolsonaro, may also review the legislation on grounds of constitutionality.

"Everything that the Supreme Court does not like, they say that this is against our constitution. It's the way that they try to get all of the power over the legislative [branch], and even sometimes the executive power. So, this is one more chapter of this long invasion by the judiciary… Lula da Silva doing the veto against this bill that was approved by the Congress only shows that he is always speaking with the left-wing bubble, he's talking to the radical left people."

Eduardo Bolsonaro believes the Brazilian people support his father over the Supreme Court, and points out that his father was not even present in Brazil for the Jan. 8 riots.

"In Brazil they do not approve [of the veto], they are fed up with all of this… On the very same day [Jan. 8, 2023]… the ‘protest dictator’, Jair Bolsonaro, was in Orlando, in Disney World. So everybody knows this is a fake thing and no one can support any more debates around this."

"That's why Jair Bolsonaro is in jail because if he wasn't convicted to 27 years in jail, he would be free to run, and for sure he would be the next president of Brazil. That's the only reason that he is in jail: because of political reasons. That is why when Flavio Bolsonaro gets elected in October and changes the political scenario, this will also change the scenario inside the judiciary of Brazil."

Eduardo Bolsonaro is entirely focused on his brother Flavio's 2026 presidential campaign as the means to freeing his father from prison.

"Now, I only have one role… electing Flávio Bolsonaro, and he will give the pardon to Jair. Not only to Jair, but also to me. I am accused of committing crimes in the United States because I was talking with authorities, American authorities, and they consider this an attack against the sovereignty of Brazil."

"The judge of the Supreme Court, Alexandre de Moraes, who got sanctioned by the Trump administration with the support of Scott Bessent and Marco Rubio, he blames me for that. But as he does not have the courage to sue Trump, Bessent and Rubio, he's suing me for that. So we hope that Flavio is going to get elected and then as president he has the power to pardon me, my father and more than 400 conservative people that are in jail."

While the Bolsonaros have historically performed very well in the vote-rich and wealthy southern states of Rio de Janeiro, São Paulo and Minas Gerais, they have underperformed in Brazil's poorer Northeast region, which is where Lula is originally from.

Yet, Bolsonaro promises a strong showing nationwide, and says that voters in the Northeast are ready for a change:

"It's bringing the truth. People nowadays know that the ‘assistencialismo’ (populist social assistance for purposes of vote-buying), that is the way that Lula gets this high amount of votes in the Northeast of Brazil."

"We are also going strong in the Northeast. The Northeast, you're going to see, it's not anymore a region of Brazil that is under the [control of] Lula."

Eduardo Bolsonaro weighed in on recent U.S. military action in Venezuela, and pledged a renewed U.S.-Brazilian geopolitical relationship, and full support for American action against Communist regimes:

"Maduro is not the president anymore and in Nicaragua Daniel Ortega arrested seven opponents… that were running for president. How can you consider this a democracy? So, for sure, it's not a democracy. There is no difference between these guys and Chapo or Pablo Escobar. The difference is only that Nicolás Maduro and Daniel Ortega took over the country, they took over the institutions."

"So everybody, not only Venezuela, but also Brazil, is really happy that the great military of the United States arrested Maduro… It's bringing hope to the people. And for sure, we do support them, not only in public… but also in international forums."

British Prime Minister Keir Starmer announced the United Kingdom will deploy its aircraft carrier strike group to the North Atlantic and the High North later this year, marking a show of force as security tensions escalate across Europe.

Speaking on Saturday at the annual Munich Security Conference in Germany, Starmer said the mission would be led by HMS Prince of Wales and carried out alongside the U.S., Canada and other NATO allies.

"I can announce today that the U.K. will deploy our carrier strike group to the North Atlantic and the High North this year, led by HMS Prince of Wales, operating alongside the U.S., Canada and other NATO allies, in a powerful show of our commitment to Euro-atlantic security," Starmer told the high-profile forum aimed at strengthening European defense and diplomatic ties.

The High North — a term referring to the Arctic and surrounding regions — has become increasingly strategic amid growing Russian military activity. 

The deployment is intended to bolster security against potential Russian threats, according to BBC News.

The announcement comes as President Donald Trump has repeatedly reiterated interest in the U.S. acquiring Greenland, citing national security concerns in the Arctic regarding Russia and China.

Starmer warned that Moscow’s military buildup could intensify even if a peace agreement is reached in Ukraine, arguing that Russian rearmament would "only accelerate."

Europe, he said, must be prepared to "deter aggression" and, if necessary, be ready to fight.

"We must build our hard power, because that is the currency of the age," he said.

The carrier strike group is an international naval task force led by the Royal Navy. It consists of one aircraft carrier, about 40 aircraft, a frigate, a destroyer, a submarine and a supply ship, according to BBC News.

HMS Prince of Wales, a roughly $3.5 billion aircraft carrier, serves as the Royal Navy’s flagship, BBC News reported.

TROOPS FROM EUROPE DEPLOY TO GREENLAND IN RAPID 2-DAY MISSION AS TRUMP EYES US TAKEOVER

Trump has previously threatened tariffs on Britain and other European countries unless an agreement is reached allowing the U.S. to take control of the Danish territory. 

After meeting with NATO Secretary General Mark Rutte in late January, Trump announced that he would not impose tariffs that were set to take effect Feb. 1 given they formed the "framework of a future deal with respect to Greenland and, in fact, the entire Arctic Region."

Trump told reporters outside the White House on Friday that the administration is "negotiating right now for Greenland," adding that, "We get along very well with Europe." 

The president was also asked about the Munich Security Conference.

"If it wasn't for me, they'd be paying 2% and not paying," Trump said of NATO allies. "They're paying 5% and they're paying. We have a very good relationship with NATO."

The three-day Munich conference brings together world leaders, defense chiefs and security officials.

Starmer did not immediately respond to Fox News Digital's request for comment.

Rep. Alexandria Ocasio-Cortez, D-N.Y., alleged at the Munich Security Conference on Friday that U.S. aid to the Jewish state enabled a genocide against Israel. AOC’s attack on the Jewish state in Munich unfolded in the birthplace of Adolf Hitler’s Nazi movement that carried out the worst genocide in human history.

AOC’s assault on Israel’s war campaign to defeat the U.S. and EU-designated terrorist movement in the Gaza Strip sparked outrage and intense criticism from academic military and Middle East experts.

During the town hall event in Munich, the Squad member said, "To me, this isn't just about a presidential election. Personally, I think that the United States has an obligation to uphold its own laws, particularly the Leahy laws. And I think that personally, that the idea of completely unconditional aid, no matter what one does, does not make sense. I think it enabled a genocide in Gaza. And I think that we have thousands of women and children dead that don't, that was completely avoidable."

She continued, "And, so I believe that enforcement of our own laws through the Leahy laws, which requires conditioning aid in any circumstance, when you see gross human rights violations, is appropriate."

The Leahy Laws prohibit the Department of Defense and the State Department from funding "foreign security force units when there is credible information that the unit has committed a ‘gross violation of human rights." Former Sen. Patrick Leahy, D-VT., introduced the bill in 1997.

Tom Gross, an expert on international affairs, told Fox News digital that "AOC has flown all the way to Munich — infamous as the city in which Hitler staged his Nazi Beer Hall Putsch that marked the beginning of the road to the Holocaust — in order to smear the Jewish people further with a phony genocide allegation."

Gross added, "Such preposterous allegations of ‘genocide’ form the bedrock of modern antisemitic incitement against Jews in the U.S. and globally. This shocking ignorance and insensitivity by Ocasio-Cortez should rule her out of any potential presidential bid or other high office."

RASHIDA TLAIB HIT WITH HOUSE CENSURE THREAT, ACCUSED OF 'CELEBRATING TERRORISM' IN PRO-PALESTINIAN SPEECH

Military experts and genocide researchers have debunked the allegation that Israel carried out a genocide against Palestinians during its self-defense war against the Hamas terrorist organization that started after Hamas terrorists attacked communities in parts of southern Israel on Oct. 7, 2023 that saw over 1200 Israeli and foreign nationals killed and 251 brutally kidnapped and taken into Gaza by Hamas and other terrorists.

Danny Orbach, a military historian from the Hebrew University of Jerusalem, and co-author of "Debunking the Genocide Allegations: A Reexamination of the Israel-Hamas War from October 7 2023, to June 1, 2025," told Fox News Digital that Ocasio-Cortez accusation that Israel committed genocide is an "accusation that is incorrect both factually and legally. Under the Genocide Convention, genocide requires proof of a special intent to destroy a protected group, in whole or in part, and as a baseline condition, an active effort to maximize civilian destruction.

"The evidence shows the opposite: as demonstrated in our multi-author study Debunking the Genocide Allegations, Israel undertook unprecedented measures to mitigate civilian harm, including establishing humanitarian safe zones that independently verified data show were approximately six times safer than other areas of Gaza."

Orbach added, "Israel also issued detailed advance warnings before strikes and facilitated the entry of over two million tons of humanitarian aid, often at significant cost to its own military advantage, including the loss of surprise and the sustainment of an enemy during wartime."

He concluded, "These measures were taken despite Hamas’s Oct. 7 massacre, its systematic use of human shields and hospitals for military purposes, and a tunnel network exceeding 1,000 kilometers — an operational challenge without historical precedent. Finally, no credible evidence demonstrates the kind of unambiguous, exclusive genocidal intent toward Palestinians that international law requires and that cannot be reasonably interpreted otherwise."

The conservative commentator Derek Hunter posted on X. "Imagine going to Germany to complain about a fake genocide by Jews...in Munich, of all places. @AOC is about as smart as clogged toilet."

In Dec. 2024, Germany joined the U.S. in rejecting the allegations that Israel committed genocide in Gaza.
