Donald Trump worries that Joe Biden could lead the US into World War III

The former US president has launched another vitriolic attack on his White House successor as he branded Biden as "dumb", a "lunatic" and a "mental catastrophe".

In a video shared on his Truth Social website, Trump is heard saying: "Crooked Joe Biden is not only dumb and incompetent. I believe that he has gone mad - a stark raving lunatic - with his horrible country threatening environmental open borders and DOJ, FBI weaponisation policies.

"He is a mental catastrophe that is leading our country to hell that will end up in World War III because of this man and for no reason whatsoever."

Trump is seeking re-election in 2024 despite being embroiled in a number of court cases and recently questioned if Biden would be physically capable of running in next year's poll.

The billionaire businessman mocked the president's physical stature and suggested that Biden "can't put two sentences together".

In an interview with former Fox News host Tucker Carlson, Trump said: "I don't think he gets to the starting gate, but these people do miracles.

"I think he's worse mentally than he is physically, and physically, he's not exactly a triathlete, or any kind of athlete.

"You look at him and he can't walk to the helicopter. He can't lift his feet out of the grass. It's only two inches at the White House (but) it looks like he's walking on toothpicks."
