> USA can win this war with barely any casualties

What do you mean by "win"? What strategic goals can the US achieve in this war? We're at a point where merely achieving status quo ante bellum--i.e., Iran doesn't charge for passage through the Strait of Hormuz--seems to require giving concessions elsewhere.

In many ways, this looks like the American version of Pearl Harbor--a stunning tactical victory that is simultaneously a crushing strategic loss.
