However, the list is still awaiting approval from the administration and could be subject to changes, as reported by the New York Times.

It has also been noted that the majority of the countries listed are Muslim-majority, economically struggling, and considered to have high levels of corruption.

Trump also issued a strong warning while speaking to the Justice Department.

He stated: “I think we have it, I think we have it, but this could lead to World War III, very easily, could very easily lead to World War III.

“But I think we’re in pretty good shape, a lot better than where we were before we got involved.

“That was heading into World War III territory, that would’ve been a war like no other because of nuclear weapons, and other types of weapons that you don’t even wanna know about.”

He added: “I think we’re doing well with Russia, we’re speaking with President Putin, we want to get the war over.”
