Cold War? What's that?

Seriously, you have some very good point there, but I think you missed the point I was trying to make. It doesn't take possesion of nuclear weapons to do radiation tests - not that I'm saying that purposeful exposure to radiation is a Good Thing - far from it! But I was referring to the responsibility to realize the power you hold in your missile silos, and the holocaust you would most likely trigger if you actually used those WMDs.
Look at it this way: I'm a big boy - 6'3", 200 lbs or so (1.93 meters, 102Kg). I'm told by people that I'm quite strong, but it's strength that comes with my size - I don't work out. But even so, I'm aware of just how hard not to hold an egg. In "extreme" terms, I can be responsible enough to know how much strength I should or should not use in holding on to that egg. Yeah, I make mistakes - that has nothing to do.
You cannot expect a nation to be perfect. First of all, that perfection is completely relative to every person. But secondly, mistakes happen. We can try an avoid them, but there's a reason the word is still around. Yeah, it's easy to say that the Cold War was one big mistake now, but look at it from the perspective of those people who were not only living in that time, but who had to make the big descisions at the time. Their primary job was to ensure the safety of their citizens, a task which I believe they strived towards with the utmost of their abilities and with the knowledge they had at the time.
And don't pull a CNN on me, either. I said
most WMD equipped nations. I refer to specifically the USA, Britain, France, Israel, and the like. I'm unsure about Russia, simply from a lack of knowledge about the situation. But take those four nations I listed. Can you genuinely see Saddam's Iraqi dictatorship being as responsible with WMDs as they were? Honestly?
