Here is my analysis in the event of an Israeli or Israeli-U.S. attack on Iran. The attack will likely trigger intense opposition, diplomatic or military, from these countries in the region -
Syria, Lebanon, Iraq, Bahrain (Shia majority), Afghanistan, Pakistan, India, China and Russia. And Deepak has not even begun to count Palestinians and other Sunnis who will be enraged because Israel and the U.S. will have attacked another Islamic country standing up to them, leave aside the uproar of the anti-war movements in Europe and the United States.
The troika of Netanyahu-Lieberman-Barak may be stupid not to understand this. Will Obama be so foolish or daring as to go ahead and attack Iran?
