I'd like to hear comments/theories as to why Russia backs Iran so strongly, to the point of supplying Iran with nuclear technology. Russia gives every indication of being comfortable with an Iran armed with nuclear missiles despite the proximity of Iran to Russia. Parts of Russia (including Moscow) will likely be in range of Iranian missiles before western Europe or North America are. How can the Russians be so sure that the ruling clerics won't target them for their treatment of Muslim minorities such as in Chechnya, or for Russia's prior support of Serbia against Bosnian Muslims? In any case, a nuclear exchange, involving a nuclear armed Israel, so close to Russia's borders can hardly be in Russia's interest. I know Putin's Russia still has much of a cold war mentality, but this seems somewhat like "cutting off your nose to spite your face". Why are we so worried about a nuclear Iran when they don't seem to be? What gives?
