Donald Trump in his return to the White House has already previewed his second term foreign policy approach: Talk loudly and wield a big stick.

Donald Trump is practicing not deterrence but ‘compellence,’ making a threat to coerce foreign actors into doing things we want.

Trump briefly raised the idea of buying Greenland in his first term and expressed shock—even calling off a planned visit to Copenhagen—when his offer was refused. This time around, he’s not backing down. He has held at least one reportedly tense phone conversation on the matter.

In just a week, the president has floated financial reprisals for Mexico, Canada, Russia, Denmark and Colombia. The hostilities could backfire.

As tensions between Russia and Ukraine persist, the involvement of foreign fighters continues to complicate the conflict. The capture and prosecution of these individuals have become a significant part of Russia’s legal and propaganda efforts.

The president is increasingly threatening other countries with tariffs for issues that have little to do with trade.

Oil edged lower in early trade as Goldman Sachs said the latest round of U.S. sanctions against Russia haven’t had a significant impact on the country’s oil exports.

Oil prices retreated on Monday after the U.S. pulled back from initial sanctions threats against Colombia, reducing immediate concern over oil supply disruptions, though U.S. President Donald Trump's muscle-flexing is keeping markets twitchy.

There were no Situation Room meetings and no quiet calls to de-escalate a dispute with an ally. Just threats, counterthreats, surrender and an indication of the president’s approach to Greenland and Panama.

Donald Trump claimed an early victory for a coercive foreign policy based on tariffs and hard power on Sunday after announcing Colombia had backed down in a dispute over migrant repatriation flights.

The Russian Embassy in London said that Russia posed no threat to undersea cables in Britain and other NATO countries, after UK defence minister John Healey accused Moscow of "malign activity" at sea.
