I can understand your frustration. I'm frustrated too, esp at Bush's failure to communicate to the American Public.
However, things appear to be moving in the right direction albeit slowly. We have no proof that N. K. or Iran or Syria for that matter have nukes. I think once they play their hand then the gloves come off.
Unfortunately a lot of people may die before that happens, but the world is coming around to knowing that Islam is a religion of destruction.
We disarmed the teeth of the Soviet Union without shots being fired. There are forces of freedom in Iran now that might do what you are asking our president to do with military force.
Patience is requried.. Things don't happen overnight..
You should realize that NK and IRAN are not PAKISTAN.
And said North Korea and Iran should never become today's Pakistan.
