Well, I do keep up with the news and there are thousands of U.S. troops in Afghanistan.
Let's go with your "War on Islam" theory. You state that the U.S. in "all Muslim lands"...do you mean that the U.S. is fighting every Muslim country? That is obviously false, so are you suggesting that the U.S. is only involved militarily with Muslim countries? That too is false of course, as the U.S. military is stationed throughout the world and their last military effort before the wars in Afghan and Iraq was against Christians persecuting Muslims...remember that one?
As for Gitmo, how many detainees are in Gitmo now? Maybe 150 or 200? Can't recall exactly, but not all that many in the scheme of things. They will be charged fairly speedily now that the Supreme Court has signed off on military trials.
Now, "sleeper cells". Yes, experience has taught us that those who appear completely normal in their daily lives can pull off terrorist attacks. The U.K. train bombings being only one example. That doesn't mean authorities are watching every single Muslim, as that is obviously impossible, but are concentrating on certain mosques and communities these individuals are known to frequent or have contacts. That isn't a "war on Islam", that is called criminal investigation.
