Mad Don at the UN

Of COURSE he did.

The President called North Korea’s Kim Jong Un the leader of a “depraved regime” and a “rocket man […] on a suicide mission for himself and for his regime.” He added that “no nation on Earth has an interest in seeing this band of criminals arm itself with nuclear weapons and missiles.”

“We will have no choice but to totally destroy North Korea” if the United States is “forced to defend itself or its allies,” he said.

“Major portions of the world are in conflict,” he told the assembled heads-of-state. “Some, in fact, are going to hell.”

And some are being sent there by American policy. Some may even be "totally destroyed".

Remember that you’re dealing with a population that knows very little about the outside world except what the government tells it about the outside world, and, because of that, a population that firmly believes the United States is always one step away from annihilating it and has been since the middle of the last century. Now, before god and the world, here’s an American president saying that for real. The government propaganda apparatus doesn’t even need to make anything up this time around.

And, he went after the Iran deal.

“It is far past time for the nations of the world to confront another reckless regime,” he said upon first referring to the nation, following a condemnation of North Korea. “One that speaks openly of mass murder, vowing death to America, destruction to Israel and ruin for many leaders and nations in this room.”

“The Iranian government masks a corrupt dictatorship behind a false guise of a democracy,” he said.

[...]

The Trump administration has notably abided by that deal, though, and most recently waived sanctions on Iran while determining whether to certify the country’s compliance by the next deadline on Oct. 15. Still, the President trashed the deal at the U.N.

“The Iran deal was one of the worst and most one-sided transactions the United States has ever entered into,” he said. “Frankly, that deal is an embarrassment to the United States and I don’t think you’ve heard the last of it, believe me.”

He was on a roll.

He labeled Iran a “rogue nation,” accused it of sponsoring terrorism, and said that “it is time for the entire world to join us in demanding that Iran’s government end its pursuit of death and destruction.”

Trump has long railed against the nuclear agreement put into place by President Obama, though it is still unclear whether he intends to end it.

The president referred to “loser terrorists,” who want to “tear up our nation or tear up the entire world.” And he said the world must fight against “radical Islamic terrorism,” a phrase that H.R. McMaster, his national security adviser, had pushed him for him to avoid.

Trump also asked that countries pledge help to crisis-racked Venezuela, calling for “the full restoration of democracy,” and singling out the nation’s leftward drift as the cause of its failings.

“The problem in Venezuela is not that socialism has been poorly implemented, but that socialism has been faithfully implemented,” he said to scattered laughter.

Trump’s belligerent address earned at least one fan among heads of state: Israeli prime minister Benjamin Netanyahu, who said that he had not heard “a more courageous speech” in his 30 years at the U.N.

I expect to see that in a tweet.

He's just tweeted the destruction of North Korea part.
