I agree with you Mac, and I don't want anybody to have them. But "self-preservation?" How do you preserve yourself by blowing up the Earth?
How can we be sure that North Korea and Iran will use them? Maybe the only reason they want them is because they see US as the one's that will use them for either anger or political advantage. I mean, so far we're the only ones in history that have PROVEN that we are willing to use them........
If I was North Korea or Iran, I would want them too. To protect myself from the USA. I would see the USA as a threat to me. Don't get me wrong....I certainly don't want those nuts having even a cap gun to tell you the truth.
I don't like them, and I wish we would get rid of them.
We have enough firepower and other things that would could take out ANY force that tried to build them.....so why do we still need them? Why not get rid of all of them and set the example for others to follow? Then we (not US, we don't make the rules, but the world rather) make it international law to NOT have them. If anyone breaks that law, then the rest of the world kick their ass........
