Truth? I think Trump is just so lizard brained he doesn't really understand why the Iranian leadership won't surrender. In his mind, the whole point is to fleece the oil profits so the idea that Iran would risk ANY of its oil profit over something like "soverignty" and "self determination" is crazy sucker talk.
The thing about egomaniacs is they think everyone thinks like them because the way they think is the only correct way TO think.
