Donald Trump took the stage at the United Nations general assembly hall for the first time in six years to launch a full-on assault on the world body, which he described as a feckless, corrupt and pernicious global force that should follow the example of his own leadership.

Axar.az informs, citing Guardian, in an inflammatory speech on the 80th anniversary of the founding of the United Nations, Trump called for countries to close their borders and expel foreigners, accused the UN of leading a “globalist migration agenda”, and told national leaders that the world body was “funding an assault on your countries”.

“It’s time to end the failed experiment of open borders,” he said in a headline speech to world leaders and visiting delegations in the grand general assembly hall in midtown Manhattan. “You have to end it now … Your countries are going to hell.”

Directly addressing European leaders in contentious terms, he accused them of “destroying your heritage” and of allowing international migration because of misplaced “political correctness”. Trump also attacked green energy initiatives as redistributing manufacturing power from the developed world to “polluting countries that break the rules and are making a fortune”.

“Your countries are being ruined,” he also said, pointing to UN programs that he claimed provide food, shelter and debit cards to fund immigrant journeys to the United States. “The UN is funding an assault on western countries.”

In many ways, the speech was an appeal to European leaders to embrace a blood-and-soil nationalism in which Trump laid out the recent US assault on immigration as a model for the world to follow.

“If you don’t stop people that you’ve never seen before, that you have nothing in common with, your country is going to fail,” Trump said. “I’m the president of the United States, but I worry about Europe. I love Europe, I love the people of Europe. And I hate to see it being devastated by energy and immigration, that double-tailed monster that destroys everything in its wake.”

Trump also singled out Sadiq Khan, the first Muslim mayor of a Western capital, saying: “I look at London, where you have a terrible mayor, terrible, terrible mayor, and it’s been changed, it’s been so changed. Now they want to go to sharia law. But you are in a different country, you can’t do that."
