"How stupid, what an idiotic plan, the world changes so rapidly, 2013 will look nothing like this world, what a bunch of dopes they are."
That is true. However, Hitler also counted on German world domination by 1955 and although he wasn't able to fulfill his plans, he still managed to wreak havoc big time.
So at least it's good having an idea what our enemy is up to.
There is a big difference between Hitler and these nutballs. Hitler had a realistic chance of pulling off world conquest. It is possible to point out numerous points in time where changes in his policies could have credibly resulted in his winning the war.
Nobody has yet pointed out to me any realistic scenario under which Osama and his morons conquer the world. Ain't gonna happen.
The only question at issue is how much damage we allow them to do before we destroy them. My personal opinion is that we will have to lose a city before we get serious. Very unfortunately.
