“It was not Iraq,” the president told ABC News. “It were other people. And I think I know who the other people were. And you might also.”
Almost 3,000 people died when 19 terrorists – most of them Saudis – hijacked four passenger planes on 11 September, 2001. Two of the planes were crashed into the Twin Towers in New York City, one into the Pentagon in Virginia and one was brought down in Pennsylvania after passengers fought back.
The al-Qaeda terror network, led by Osama bin Laden, claimed responsibility for the atrocity.
In an interview with ABC’s George Stephanopoulos, Mr Trump criticised America’s military intervention in the Middle East, which he said was ”the worst decision made in the history of our country”.
He described the region as “like quicksand” and added: ”It was a terrible decision to go into the Middle East. Terrible.
“We’re now up to almost $8tn (£6.4tn). And when we want to build a roadway, a highway, a school, or something, everyone’s always fighting over money. It’s ridiculous. So that was a bad decision.”
He added: “And, by the way, Iraq did not knock down the World Trade Centre. It was not Iraq. It were other people. And I think I know who the other people were. And you might also. But it was a terrible decision.”
