You miss the point, Denzel. Russian missiles on their own territory, if that was all there was to it, yes, is active deterrent. Russians threatening to, or in fact placing missiles due to an event they don't like, is hostile.
You're wrong on your second point, as well. Development of protections -has- rendered armies unstoppable due to their near-invulnerability to the weapons of the area and time. These spans of time are always limited when they happen, and they are not absolute, but the development of defenses has surpassed weaponry on a number of occasions. So sayeth the US Army Colonel in my military history class.
I'll give you that Bush is an idiot, but I appreciate having him in the office for one major reason. Through all the Clinton years, we suffered numerous terrorist attacks directed by bin Hidin', and the response was always the same- "We will find those responsible and we will bring them to justice" and nothing much ever happened. I think Osama bin Hidin' was very surprised when the whole of the US military came after his sorry ass after 9/11. Beyond that, Bush can go to hell.
You know, Denzel, you're right so often it makes me wonder how you can start at a correct point and wander so far off track so quickly. There can be no winner in a nuclear war, true. But the last country in the world that needs a nuclear bomb is Iran. They'll make one, they'll put it in a truck, and they'll drive it over to Israel. Boom. Uncounted dead, a small wasteland left in its wake, and even if you could go into the wasteland, there's no evidence left over to find out who made and sent the bomb. Congratulations, they just pulled off a nuclear strike that can't be retaliated against.
