No, that would be two reactors in North Korea.
Wrong.
You're forgetting, not just Iran, Venezuela (Chavez has extreme Communist Empire ambitions as well and wishes to nuclearize just as Iran is), Pakistan (constantly teetering on becoming Jihadistan with one well-placed bullet) etc...and the primary puppet-masters behind all this: The neo-soviet Russian Federation of Putin and the Chi-Comms.
The problem is far vaster and more treacherous than you are surmising. The Russian leadership and Chinese leadership truly intend, not just wish for, the destruction of the U.S. as a power of any kind. They truly are working extremely hard towards that end. And they will use their entire arsenals when they feel they can get away with it.
Notice that during all this...W is racing to unilaterally disarm our strategic forces. Neville Chamberlain would be proud.
Meanwhile, the Russians aren't doing squat to disarm. Instead they are busily beavering away at a whole slew of new strategic weapons...from ICBMs, SLBMs, Naval technology, Air Superiority aircraft and missiles...as are the Chi-Comms. All awaiting the day when the tables have finally turned because of the smug hubris of the West's ongoing Defense Holiday.
