Foreign Policy: on Foreign Policy

Donald Trump: Reimbursement for US military bases in rich countries abroad

Trump then got into a specific example: Saudi Arabia, one of the more important US allies in the Middle East. Saudis "make a billion dollars a day. We protect them. So we need help. We are losing a tremendous amount of money on a yearly basis and we owe $19 trillion," he said.

Walking back trade deals and agreements that allow the US military to operate overseas is easier said than done. But Trump has tapped into a powerful anti-Washington populist sentiment.

Donald Trump: Trump "an utterly disloyal ally," odious to European leaders

Danielle Pletka, an expert on international relations at the American Enterprise Institute, added, Trump "earned" the trans-Atlantic hostility that he now faces in international settings. "He has been an utterly disloyal ally, and he has been odious toward a whole series of European leaders," she said.

Ed Gillespie: Emphasize American exceptionalism; a force for good in world

Mitt Romney: Use opportunity for regime change in North Korea

"Kim Jong-il was a ruthless tyrant who lived a life of luxury while the North Korean people starved. He recklessly pursued nuclear weapons, sold nuclear and missile technology to other rogue regimes, and committed acts of military aggression against our ally South Korea. He will not be missed," Romney said. "His death represents an opportunity for America to work with our friends to turn North Korea off the treacherous course it is on and ensure security in the region. America must show leadership at this time. The North Korean people are suffering through a long and brutal national nightmare. I hope the death of Kim Jong-il hastens its end."

Steve Forbes: Taiwan: Unconditional US response defends against China

Ted Cruz: Appeasement historically leads to more violence

Instead of providing clarity, the Obama administration offers tortured semantics. The interim agreement over Iran's nuclear program is referred to as a display of "international unity." And now, the Russian invasion of Ukraine was euphemistically designated "an uncontested arrival."

This is the language of fools. Appeasement, historically, leads to more and more violence. Bullies and tyrants are only encouraged when the US uses words that willfully ignore the reality of the threats the US and our allies face.

Ironically, this administration's effort to avoid conflict at all costs makes conflict all the more likely. Putin knows there will be no serious reprisals for aggression from an American president who was only waiting for his re-election to give him the "flexibility" to make additional concessions at the negotiating table.

Joe Biden: OpEd: Ignoring Latin America is modern Monroe Doctrine

[Many Republicans] are following the lead of former U.S. President Donald Trump, who hailed Monroe on the floor of the United Nations General Assembly [to keep China out of Latin America]. Many Biden administration initiatives are perceived in Latin America in a similar light. Top US officials rarely make time for Latin America beyond issues related to immigration and drug trafficking, and the US' economic offerings to the region are seen as paltry compared to its commitments elsewhere. When Biden officials hector Latin Americans on the dangers of economic engagement with China, the warnings are heard as modern echoes of Monroe's quip that the United States knows best.

John Kerry: 2013: The era of the Monroe Doctrine is over

Even a decade ago, one might have assumed that Monroe's relevance in the 21st century had waned. It had become closely associated with U.S. Cold War interventions and unilateralism in the Americas. When then-U.S. Secretary of State John Kerry declared in 2013 that "the era of the Monroe Doctrine is over," the principle had become an anachronism.

Anticipating renewed great-power rivalry, this time with China, the seeming simplicity and persistence of the Monroe Doctrine mean that it has regained adherents in the US. Yet recent praise for the doctrine from within the Republican Party suggests only superficial understandings of the doctrine and its meanings in Latin America.

Ron DeSantis: Reinvigorate Monroe Doctrine: limit China in Latin America

Republican presidential candidates such as Vivek Ramaswamy and Ron DeSantis are calling for the doctrine's reinvigoration to take aim at China's growing presence in Latin America and are offering it as a justification for a potential U.S. military attack on criminal organizations in Mexico. They are following the lead of former U.S. President Donald Trump, who hailed Monroe on the floor of the United Nations General Assembly, as well as advisors such as John Bolton and former Secretary of State Rex Tillerson.
