I agree, the Sunni Arabs will be a hooten and hollering for a while because it's a requirement but in reality they wouldn't mind seeing Iran kicked down a few notches.
The mullah's will be worried about their own backyard too because 85% of the population do not support them and the students of Iran could revolt and topple the government.
After the Osirak raid, didn't the other Arab nations publicly denounce the attack yet privately thank Israel?
