Hmm let's examine how well the US sanctions against China and Russia are working, shall we?

Forget those, how well are the vaunted US sanctions working against Iran?

Why do you say "no matter what"? It's pretty clear things are going pretty badly for the USA? Last time they went into the Middle East, they steamrolled their enemy in weeks.

Now they're running low on ammo, without having accomplished anything of strategic value...

Invasion seems untenable given the leadership and strategy we are seeing in this giant Iran defeat.
