As Donald Trump gets ever closer to becoming the presidential nominee for the Republican Party, foreign leaders have become increasingly vocal about what a Trump administration would mean to them.

David Cameron

In December 2015, shortly after Trump called for a ban on all Muslims entering the United States, British Prime Minister David Cameron said Trump’s remarks regarding Muslim migrants were “divisive, stupid and wrong.”

Although many British citizens were calling to ban Trump from the U.K., the Prime Minister did not feel that the real estate magnate turned politician should be barred from entering.

Cameron suggested that if Trump were to visit the U.K. his presence would only act to stir people towards solidarity against his xenophobic politics. “If he came to visit our country I think he would unite us all against him,” said Cameron.

Angela Merkel

Trump has derided German Chancellor Angela Merkel's welcoming stance on refugees as "insane" and said that her immigration policies would eventually lead to social unrest and rioting in her nation.

Merkel has voiced how little she thinks of Trump’s attacks by simply refusing to reply.

The leader informed German media that she could see no reason why she should respond to Trump and that she was, in fact, a fan of Democratic candidate Hillary Clinton.

"I value her long political experience, her commitment for women's rights, family issues and health care,” said Merkel, adding, “Whenever I had the chance to work together with Hillary Clinton, it was a great pleasure."

Vladamir Putin

Vladamir Putin, who Trump has praised in the past, has called Trump the “absolute leader” of the current presidential race.

The 63-year-old Russian leader described Trump as "a bright and talented person without any doubt. He is the absolute leader of the presidential race."

Enrique Pena Nieto

Perhaps the most strident remarks regarding Trump have come from Mexican President Enrique Pena Nieto.

Discussing Trump’s campaign promise to build a border wall and have Mexico pay for its construction, Pena Nieto said he can see of no scenario in which this would happen.

The Mexican leader has deep concerns about maintaining the productive and mutually respectful climate that Mexico and the U.S. have typically enjoyed.

Pena Niteo compared Trump’s inflammatory tone to the rhetoric of fascist leaders such as Hitler and Mussolini.

The 49-year-old leader explained that there have been episodes in history when Trump's kind of extreme language has resulted in dark periods for humanity.

"That's how Mussolini got in, that's how Hitler got in, they took advantage of a situation, a problem perhaps, which humanity was going through at the time, after an economic crisis," Pena Nieto said.

Diplomats in Distress

Diplomats from Europe, the Middle East, Latin America and Asia have all reportedly voiced private complaints to U.S. officials about the inflammatory statements made by Trump.

Elliott Abrams, the senior fellow at the Council on Foreign Relations, has summed up the situation as one of confusion and worry.

"All foreign diplomats I’ve talked to are amazed at the Trump phenomenon and worried about it, especially in the Middle East and Europe,” said Abrams.
