Why is Obama talking about a decrease in nuclear arms?
Because it's the right thing to do. Both sides have enough weapons to wipe each other out many times over. They are a hold over from the era of mutually assured destruction. Nuclear war is not an option for any country... never really was.
But, terrorists would love the weapon, and Russia's security for both the weapons and radioactive materials is dicey at best. The US has spent billions in Russia since the fall of the communist regime to insure the security of Russian nukes.
No way that the US will ever use a nuke on Iran or North Korea. For Iran it would forever doom any possibility of a middle east agreements and would create a world depression that makes what we are in now look like a cakewalk. North Korea is a client country of China. If they were nuked by us, you can bet there would be retaliation. It aint gonna happen.
Best thing that could happen is get rid of the whole damn mess. Reduce the threat of inadvertent launches and terrorist threat. You know what a 20 kiloton bomb did in Hiroshima and Nagasaki... do you really think there is any situation where the US could drop a 20 MEGATON (that's 1000 times as large) bomb?
Two days in a row I find myself agreeing with Eagle, which would normally make me wonder if I was feeling well, if not for the fact that I only partially agree with his previous assertion! Clearly it is the right thing to do...for the reasons he stated above, the foremost being Russian security (which I suspect may be better now that they have Petro dollars, than immediately after the soviet empire fell) of their arsenal.
From a strategic standpoint, if we can reduce missiles 1-1 with the Russians it is to our advantage since that would increase the effectiveness of our missile defense system....which is precisely the reason the Russian will not go along with it as long as the the missile shield remains in play. Here is the part that worries me about this President negotiating on our behalf, is that it would not surprise me if during the negotiations he drops his pants, grabs his ankles and bargains away our missile defense shield (part of the same defense shield that was just deployed to Hawaii to protect us from a would-be stray North Korea missile).
I respectfully disagree that nuclear arms are off the table for Iran and North Korea. I do not think that a nuclear strike against North Korea would result in China unleashing their missiles on the US...for the very reason you stated above...it would result in mutual destruction when we retaliated against China. A limited nuclear engagement with North Korea would not be a good thing obviously, however China is smart enough to realize that everyone (except Kim Jong IL) could recover from it. As you correctly stated in one of your earlier posts....China would be more worried about containing the North Koreans flooding their borders.
