GOP frontrunner Donald Trump is making waves in America, and his campaign events are drawing massive crowds.

 With the GOP convention this summer, the chance of a Trump nomination appears likely.

Here’s how 6 world leaders feel about ‘The Donald.’

                British Prime Minister David Cameron:

After Trump’s comments on Muslims:

“I think his remarks are divisive, stupid and wrong. If he came to our country, I think he would unite us all against him.”

                Mexican President Enrique Pena Nieto:

WASHINGTON, DC - NOVEMBER 27: Mexican President-Elect Enrique Pena Nieto delivers brief remarks after meeting with Democratic members of the House in the Rayburn Room at the U.S. Capitol November 27, 2012 in Washington, DC. Nieto, of Mexico's Institutional Revolutionary Party, will also visit the White House and meet with President Barack Obama today, days before he takes office on December 1.

On Trump’s wall policy, among other things:

“I have to say that I regret (the plan), and of course, I can’t agree with this American        politician’s position.

And there have been episodes in human history, unfortunately, where these expressions of     this strident rhetoric have only led to very ominous situations in the history ofhumanity.

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.”

                 Saudi Prince Alwaleed bin Talal:

Saudi Prince Alwaleed bin Talal holds a press conference in Kuwait City on April 24, 2011 to announce an agreement has been reached on returning most of his disputed agricultural land in Egypt back to the government.

                 “He is a bright and talented person without any doubt.”

                French Prime Minister Manuel Valls:

LONDON, ENGLAND - OCTOBER 06: French Prime Minister Manuel Valls meets with Prime Minister David Cameron (unseen) at 10 Downing Street on October 6, 2014 in London, England. M. Valls is on a two day visit to London

                   “Mr. Trump, like others, has a hatred and amalgam: our only enemy is radical Islam.”

                Geert Wilders, Leader of the Party of Freedom in the Netherlands:

BERLIN - OCTOBER 02: Dutch right-wing politician Geert Wilders greets supporters upon his arrival on October 2, 2010 in Berlin, Germany. Wilders came on the invitation of German renegade former Christian Democrat (CDU) Rene Stadtkewitz, an outspoken Islam critic, to speak to approximately 500 supporters in Berlin. Wilders is seeking to create an international alliance of critics of Islam, called the "International Freedom Alliance," in Germany, France, the United Kingdom, Switzerland, Denmark, the United States and the Netherlands.

                 “Good for America, good for Europe. We need brave leaders.”

many political and world leaders have made their opinions known about Trump, there are still several who have yet to do so. If Trump wins, however, that’s sure to change.
