Just extrapolating your nonsense
It's not nonsense, no one ***** with the nuclear powers because having a Bomb is the most effective deterrent to invasion ever invented.
You're a little whacked out and confused here... because we dropped nukes on Japan and yet never INVADED them, and most likely that is what any other nation would do as well, because one, there's nothing left, and two, the remaining radio activity would kill the invaders. So having nukes is NOT that effective of a deterrent to INVASION.
Now, to point out the nine hundred pound gorilla in the room, the MOST EFFECTIVE DETERRENT TO INVASION is an ARMED NATION, such as America. THAT is why we've never been invaded, and why we never will be invaded, because practically our entire populace is ARMED.
