Well, the argument there is that such an attack hasn't happened because we have such advanced weapons and well trained and equipped forces etc.
Didn't the USA consider invading us after WW2? I'm sure the French would be all over us if let our guard down for a second
Don't get me wrong, I fully understand what your saying, I'll probably be voting Green myself, but I think whilst modern puppet politics still exist and big business goes around the world dicking anyone worth stealing from, I'm happy we have big clever guns, which again, I know it's a self perpetuating argument. I think the change needs to be a bit slower and other things need to change before we get rid of our nukes.
No need to get rid of things we've already paid for, especially if they're such an important player in world peace, but how can you improve on such a magnificent array of weaponry that could send civilization back to the stone age? You can't improve perfection lol
The US have invaded us, we're like their largest military base in case the east decide to attack them.
