The comments came after the President of the United States addressed the United Nations, where he told European leaders, "your countries are going to hell", and praised himself for "ending seven wars."

During the hour-long address, the 79-year-old admitted that ending the war in Ukraine was harder than he had expected.

"There are always lots of surprises both good and bad," he said, following comments that he thought his relationship with Russian President Vladimir Putin would help end the war.

The US President also said Europe was "on the brink of destruction" due to the green energy agenda and branded climate change the "greatest con job ever perpetrated."

While RTÉ [Ireland's national broadcaster] reports that the speech was met with various stony silences and shock, UN High Commissioner Ms Robinson was open about her disdain for Trump’s comments.

Speaking on Channel Four News, the former Irish president said Trump’s comments on climate change were "incredibly stupid [and] incredibly reckless."

She said: "To have the leader of the United States say in the UN that this is stupid or chaotic, or the words he used, is really heartbreaking, because we need to move in the other direction."

Ms Robinson expressed her hopes that the EU would "follow through" on its commitment to reduce greenhouse gas emissions by 90% by 2040.

Questioned on Trump’s opinions on Gaza, she said it was "a human-induced famine" where children are dying of malnutrition.

She said, "He is largely responsible because he’s supporting Prime Minister Netanyahu. The United States is complicit in this famine and unfolding genocide; it’s on his watch."

President Trump insisted he deserved a Nobel Peace Prize for ending several wars, with Ms Robinson responding, "all he has to do is stop Prime Minister Netanyahu from being such an extremist leader of his people."
