With this same train of logic, why not just let Israel push the Muslims into the sea? (With no American and European ships to rescue them this time.) They actually can do it. Anytime, within few days if they want. One less of your world problems.

Did you ever entertain the idea the Muslims "are much better at tricking you into thinking that they're the good guys"?

Israel wouldn't really rot without the American aid, but without the American aid the Palestinians would literally starve.
