Cardinal O'Brien on Nuclear Weapons

[Anthem]

If the US had no nuclear weapons, Russia and China wouldn't need to "nuke" us, all they'd have to do would be to threaten to nuke us.  I can think of many things that Russia and China would want from the US and may very well get using nuclear blackmail. 

I will agree that the use of a nuclear weapon is almost always morally wrong since it indiscriminately targets civilian population, but we live in a world with walls and those walls have to be guarded by nuclear weapons.  I don't think merely possessing these weapons as a deterent is immoral and that is where I disagree with the Cardinal.

So, DrBombay, Putin would be like "Hey Obama, give me all your grain/oil/timber or I'm going to nuke your country into a sheet of glass"?  Thank goodness Putin would then realize, "Hmm..if I nuke them, they probably won't be producing much grain/oil/timber anymore.  Perhaps I should just invade.  But wait, we would get slaughtered."
