Il Nuovo Postiglione - How Donald Trump weaponized tariffs

Tariffs, just as they were during his first term from 2017 to 2021, are Trump's weapon of choice on the global stage.

While it may be too early to tell how successful of a tactic they are against both US allies and rivals such as China, it shows how Trump -- who prides himself on his negotiating skills -- will not hesitate to take a hard line to get what he wants.

- 'Leverage' -

After a rollercoaster Sunday with dueling tariff threats between Washington and Bogota, the White House said Colombian President Gustavo Petro had backed down and accepted the terms of repatriating immigrants from the United States.

Trump had first threatened to levy 25 percent tariffs on all imported Colombian goods in a heated response to Petro refusing to accept two military planes carrying deported migrants.

It was not clear whether leftist Petro had conceded his demand that the migrants be treated "with dignity."

Planes sent by Bogota to ferry the migrants would nonetheless return by Monday or Tuesday "at the latest," according to Daniel Garcia Pena, Colombia's ambassador to the United States.

Eddy Acevedo, chief of staff at the nonpartisan Woodrow Wilson Center think tank, said Petro "quickly became aware of the amount of leverage the United States has with Colombia and that his reckless decision could jeopardize."

"Last year alone, Petro had no problem allowing in 14,000 Colombians that were deported from the United States back to Colombia," Acevedo said.

- 'America First' in action -

White House spokeswoman Karoline Leavitt was quick to declare victory Sunday, saying: "Today's events make clear to the world that America is respected again."

Trump himself echoed the sentiment on Monday, telling reporters on Air Force One that "it serves the world well to look at" the Colombia spat.

Trump's plan for mass deportations of migrants has put him on a potential collision course with governments across Latin America, the original home of most of the United States' estimated 11 million undocumented migrants.

"The message that's being sent is how willing the Trump administration is to use these tools, and the fact that they got the opportunity to make that point in the first week of the administration, I'm sure, is quite pleasing for them," said Kevin Whitaker, the former US ambassador to Colombia who now serves as a non-resident fellow at the Atlantic Council.

True to the promises he made on the campaign trail, Trump spent his first week back in power working to implement his "America First" diplomatic credo.

In doing so, he has also threatened to levy tariffs against Canada and Mexico if they did not comply with his immigration demands.

He also announced the United States' withdrawal from the Paris climate agreement and the World Health Organization (WHO) during a slew of executive orders he signed.

In addition, Trump ordered a pause to US foreign aid -- except for Egypt, Israel and emergency food aid -- until a complete review is performed to see if it aligns with his agenda.

Trump has also threatened to "take back" control of the Panama Canal, claimed it was in Canada's best interest to become the 51st state, and reaffirmed his desire to annex Greenland, an autonomous territory of Denmark.

In the latter case, Trump has brandished tariffs against a fellow NATO ally.

And at the Davos forum last week, Trump in a videocall told the audience of business leaders to be prepared to come and produce goods in the United States, or else get ready to pay tariffs.
