"The Soviets were a country, not a religion. You do not defeat an ideology like his by creating more than a billiion enemies."
There is some thought in your post, but you are too quick to assume you are correct. Marxism is worship of government. That was Marx's ultimate goal. And you can see the worship of government in the left.
And you are correct that there are a billion muslims. It is no laughing matter to nuke Mecca. Once we are attacked by a nuclear strike, we must wipe out all major strongholds, not stopping with Mecca. There would be severe economic consequences, but we cannot tred lightly once we are nuked.
What was your old screen name?
As for billions being against us? If the root and supposedly invincible city of Mecca were to be destroyed, that might take a lot of fervor out of a religion that preaches that the city is invincible and Allah would protect it.
