Mexican President Enrique Peña Nieto compared Republican frontrunner Donald Trump with dictators, such as Adolf Hitler and Benito Mussolini for his “strident tone,” on Monday. He also said that Mexico will not pay for the wall at the US border which was proposed by Trump.

Peña Nieto further said that Trump has already damaged the relationship between the two countries with his comments.

“There have been episodes in human history, unfortunately, where these expressions of strident rhetoric have led to very ominous situations,” the Guardian quoted Peña Nieto as he told the Mexican newspaper Excélsior in an interview published on Monday. “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.”

Trump had vowed to build a wall between US and Mexico in his campaigns to keep out illegal immigrants, drugs and at the same time make Mexico bear the expenses of building it. However, at a recent GOP debate, Trump said he would be softening his stand on immigrants and will also consider reducing the size of the wall.

The President said Trump’s campaigns gave easy and simple solutions to problems which are not so easy to solve.

“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 of humanity,” the Mexican president said.

“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. And I think what (they) put forward ended up at what we know today from history, in global conflagration. We don’t want that happening anywhere in the world.”

Peña Nieto was clear that there was no scenario under which Mexico would pay for the wall if Trump became the President.

“There is no scenario,” the NBC News quoted him as saying. “I have to say that I regret (the plan), and of course, I can’t agree with this American politician’s position.”

From beating pinatas that resemble Trump to creating memes and circulating them on social media, the Mexicans started mocking Trump in various ways since his comments. Politicians are also being vocal on the issue, including ex-president Vicente Fox.
