At the moment the Iranian regime has the initiative.
They have many options before them and could prove very costly to the US.
If we bomb Iran and leave the regime in place like we did earlier in Iraq it would likely have a similar effect the 9/11 did on America.
Iran has threatened that if referred next week to the UN Security Council, they may close the St of Hormuz.
Then all hell would break loose.
I think that would be best, then. The "International Community" will not like having military action taken against it when diplomacy was still underway. We could build a consensus for action around the Iranians closing the straits. The Korean War (Russia and China abstaining) example comes to mind.
Thanks for your thoughts.
