Traditionally, Russia considers Iran under its sphere of influence but it remains unclear what Russia would do beside stalling with its veto. Under Iran's sphere of influence, however, is definetely Syria and the Hizbollah in Lebanon. Add Gaza and the Occupied Territories, stir, shake, and mix and you get a continuous theather of war from the Mediterranean Sea over Iraq (it's mainly Shia, you dolt), to Iran, Afghanistan and Pakistan. Do you want Israel to commit suicide? Really? And then consider the opinions in the rest of the Muslimic world - I bet the grievances against the Shia dim in comparison to the opportunity to hit back at the US and its cronies...
