Most likely Israel would be busy invading Lebanon and Syria, and the US will have the 'help' of Saudi etc instead unless they get them to go draw an F15 in the corner while the adults are working. Six months later we'll get "who would have thought international relations were this complicated?"
It certainly doesn't help that the only time the US media as a whole ever gets behind Trump is when he's firing missiles at people. The preference for stupid 'strength' over nuanced sense isn't just from Trump.
Israel trying both would be a disaster, I would wager, as well. Heck even one.
....You guys do realize that we fight Israel wars instead of themselves?
