Please let this be true.
You are wishing for a nuclear war? Praying for it? Iran's nuclear facilities are distributed, hidden, and buried deep. Nothing short of a full scale invasion and an occupation lasting some months could comprehensively destroy the bulk of them. The only other way to stop Iran getting nukes would be to lay waste the cities, killing the people who work in the facilities and destroying the industrial base that makes that work possible. Killing, into the bargain, hundreds of thousands if not millions of civilians who didn't {actually} vote for Ahmadinejad.
Even so-called tactical nukes would kill tens of thousands if not hundreds of thousands of civilians, all that without even setting back Iran's nuclear program that much.
Considering the cost to Iran of launching a first strike, isn't it more likely that even if Iran does get nukes, it will follow the lead of all other nuclear powers and keep the bombs as insurance?
