Vicente Fox is not one to mince words when it comes to the U.S. president.

Over the past months, the 74-year-old former president of Mexico has somewhat sealed his reputation as a fierce opponent of Donald Trump's policies -- reiterating that Mexico will not pay for the wall, for example.

His most recent rant is about Trump's decision to get rid of the Deferred Action for Childhood Arrivals (DACA) scheme, which protects children of illegal immigrants in the U.S. from being deported.

First, Fox tweeted at Trump calling DACA "the top of the vilest acts you've pulled off":

And then, in full Fox style, he recorded a video in which he delivers a massive slam dunk on Trump who "didn't even had the balls to say it [DACA cancellation] himself":

"Trump you have failed America cancelling DACA," he says.

"It is the worst action you've ever done against the ones that cannot defend themselves. This measure is cruel and heartless, worse than any machine. You're cancelling the future of 800,000 children and young people."

"You're so mistaken," he continued. "The future of any countries is in the minorities which will be majorities in a few years. You cannot stop the change, the progress, the future of that great nation. I hope your grandsons will never be in this terrible situation."
