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.
Documents? Links to back this up....?
Changing context doesn't cut it. I was talking about North Korea. Last time I checked, Hugo Chavez didn't have the capability of making enriched uranium in North Korea.

No, it's not. I was talking about North Korea, not Venezuela, or Brazil (which you don't mention and has also expressed nuclear ambition), or Mexico (which has closet deals with the Chinese), or Panama...
I not saying we don't need missile defense and never did. I am saying that relying upon missile defense to preclude nuclear attack is foolish. It won't be sufficient and we'd best do the easy stuff or we won't have time for it to become effective. Get a grip.
We here in the US are fairly lame when it comes to history. We know a little bit about our own, and that's about it. Few alive today realize or recognize how closely today's mass attitudes, government policy and military realization strategies mimic those of the UK, 1919 - 1938. Our late summer 1940 still looms. We've never before experienced anything like that - Pearl Harbor and 9/11 were miniscule in comparison. I think that's part of the problem. Most people cannot comprehend what something like that (but, given today's technology, far worse) would be like.
