On one hand, my expectation is that this is a repeat of the Syria strike. People get mad, neocons crow about it, but nothing major is done and Trump refuses to do a regime change war.

On the other, it's a travesty that Trump hasn't realized that appeasing the neocons gets you nothing. They hate him unconditionally, and every concession is just something they can use to separate him from his base and make him an easier target in the future. While Levin and his buddies certainly want more dead American kids in the Middle East for Israel, I think the fact that allowing U.S. involvement in an Iran regime change war would completely destroy Trump's legacy is at least half the reason they're salivating at this.

It's also up in the air what happens here since Netanyahu's political survival (and probably his freedom) depend on keeping Israel in a state of constant war, which means dragging the U.S. into a war with Iran seeing as they aren't winning the missile exchange and have no way to conclude it without real war. Either Netanyahu gets kicked out of office or the U.S. gets dragged into a war, at least in his mind.
