I view things a little differently. To me, radical Islam is a cancer. When you attack cancer head-on, you may get the tumor (sleeper cell) but the disease all too often pops back up.

I think they need to be starved of recruits. In the same way that new cancer treatments are working at starving cancer cells by depriving them of a food supply, we should be looking at how someone goes from "normal" to sociopath.

That way, in addition to fighting them head-on for the immediate victory, we can also work towards there being no resources for this cancer later.

And just for the record, there was a lot of resistance fighting against the Nazis. It's just hard when you're a poor east European Jew to argue with the SS officer who has a gun pointed at you telling you to get on the train.
