It would be our fondest desire. The best way to end the WOT is to have the Sunni street backing a US-led support of an Iranian revolution. An Iranian Shiite attack on any Sunni country would be like manna from Heaven for the US.
Depends on whether or not the Arab street believes the Iranians are their best shot at doing away with Israel. The enemy of my enemy is my friend, and all that.
