We’re not about to invade Iran. Impose a no-fly zone on Iran, maybe. But I wouldn’t call that a major war. More a matter of plinking away at Iranian assets until their air defenses are gone. After which the nuclear facilities are destroyed one by one along with any military hardware they use in order to challenge this no-fly zone. Think Desert Storm without the ground engagements. Unless the Iranians want to come out and play, in which case our guys would kill them by the tens of thousands.
Because it worked so well in Libya?
