Trump’s biggest weakness (and strength) is he believes he can make a deal with anyone.
No movement in the Middle East for decades, then Trump signs The Abraham Accords, because he believes in making deals. A historic success.
Trump supports a Romney as party chair, because he believes in making deals. She stabs him in the back.
Trump’s approach is “I can be your best friend, or your worst enemy.”
That’s what he did with Putin and Kim Jong-Un.
