Why Aren't Saudi Arabia And Israel Fighting ISIS And Sterling Archer?

The vile cowards in Saudi Arabia and Israel have some of the biggest, most modern military infrastructures on the planet, so why don't we let them take out the trash in their own neighborhood and crush the cretinous primitives who call themselves ISIS?  ISIS is not at all a threat to the USA; they can't do anything to harm us, but they are pissing in the punchbowl over there.  Not our problem.  Decrapitating a coupla news boys is not an act of war.  It's time for the Saudis and the Israelis to stand up for themselves.  When ISIS can be at least as annoying as a parking ticket anywhere in the lower 48, then we should consider squashing them.  Until then, let our vassal states in the Middle East do the heavy lifting for once.
