The US will either have a long and painful and ultimately unfruitful ground war, or will have to accept some of Iran's terms for a ceasefire which will leave Iran in a stronger geopolitical situation than before the war.

A third option is for the US to throw Israel under the bus and either cut military funding to them, or force them to contain themselves by treaty, join the nuclear non-proliferation treaty, and so on, under that threat.

Since Israel have been goading for this war, spoiling any diplomacy (by killing the Iranian diplomats), and seem to have no intention of ceasing fire until Iran is completely fractured, I think they are the ones who need to be stopped.

Iran would perhaps re-agree to the terms and inspections they were previously under if Israel were also forced to submit. America would then re-establish it's authority in the region to some extent.
