Former President Donald Trump warned that World War III could break out over Ukraine or Taiwan.

Asked by radio host 77 WABC what keeps him up at night. Trump said most of all he thinks about World War III because of the horrible things that are happening in Ukraine. It looks like it's going to happen in China with Taiwan.

Commenting on the Russian president's latest speech in which he promised to use every means at our disposal to protect Russia and our people, Trump said that we are in the most dangerous time, maybe in many, many years, because of the power of nuclear weapons.

It's cavalier for a major country equal to us in nuclear power to throw around words like that. This is a very bad time. A very bad time for this country and a very bad and very dangerous time for the world, Trump said, reiterating that if he were still president, Putin would not have invaded Ukraine."

He got along very well with Putin. He talked to him. He understood him, Trump said of the Russian leader.
