This is part of why it took over 40 years for Israel to finally find a U.S. president ignorant enough to pull something like this.
Might not be ignorance. There's still the strong possibility that "blackmail material" is floating around due to the island of one of Trumps old friends.
On the other, he did deny the affair with Stormy Daniels, so perhaps he's easier to blackmail than I think he is?
I wouldn't put it past him to go to war to protect such secrets, if he can conceivably frame it as something positive.
