BERLIN — German Vice Chancellor Lars Klingbeil assailed U.S. President Donald Trump for his rhetoric on Greenland and actions in Venezuela, saying the situation is worse than politicians like to admit.

The comments lay bare divisions inside Germany’s governing coalition over how to handle Washington as transatlantic tensions mount, and mark a divergence between Klingbeil’s approach and that of German Chancellor Friedrich Merz, who’s tried to maintain good relations with Trump.

“The transatlantic alliance is undergoing much more profound upheaval than we may have been willing to admit until now,” Klingbeil said Wednesday in view of Trump’s assertion that the U.S. needs control over Greenland as well as the U.S. administration’s decision to militarily seize Venezuelan President Nicolás Maduro.

“The transatlantic relationship that we have known until now is disintegrating,” he added.

Such direct criticism contrasts with the approach of Merz, who has taken a far more cautious approach to Trump of late in an effort to avoid a rupture with Washington.

With regard to Greenland, Merz has said that the U.S. president has legitimate security concerns that NATO should address in order to achieve a “mutually acceptable solution.” While other EU governments strongly criticized the Trump administration following the capture of Maduro, Merz was restrained, calling the matter legally “complex.”

Behind Klingbeil’s more strident criticism of Trump, there’s a clear political calculus. The vice chancellor — who also serves as finance minister — is a leader of the center-left Social Democratic Party (SPD), which governs in coalition with Merz’s conservative bloc and has seen its popularity stagnate. Attacking Trump more forcefully may be one way for the party to improve its fortunes.

Polls show most Germans strongly oppose Trump’s actions in Venezuela and his rhetoric on Greenland, and views of the U.S. government more generally are at a nadir. Only 15 percent of Germans consider the U.S. to be a trustworthy partner, according to the benchmark ARD Deutschlandtrend survey released last week, a record low.

This underscores the political risk for Merz as he seeks to avoid direct confrontation with an American president deeply unpopular with the German electorate. But Merz has calculated that keeping open channels of communication with the U.S. president is far more critical.

Klingbeil, on the other hand, is less encumbered by international diplomacy.

“The Trump administration has made it clear that it wants to dominate the Western hemisphere,” he said on Wednesday. “One could sit here and say, ‘Yes, what the US has done in Latin America is not pretty. Yes, there are also threats against Mexico, Colombia, and Cuba, but what does that actually have to do with us?’ But then we look at President Trump’s statements today about Greenland. Then we look at what the Trump administration has written in its new national security strategy with regard to Europe.”

“All the certainties we could rely on in Europe are under pressure,” Klingbeil added.
