Because disrupting energy exports is the easiest way to pressure their aggressors and most of the states are openly supporting the US. They get bombed to hell anyways because there was no real plan besides hoping for submission after the decapitation strike so they will make it hurt for everyone else.

The middle eastern states are diverting investments into the us. Look at a map there is no way the US can effectively put boots on the ground the whole country is a natural fortress. It would be a worse disaster than Afghanistan.
