Sometimes you just have to win

Consul at Arms pointed out this which is very worth sharing:
John Matel's The Meaning of Our Victory in Iraq. Quote:

Sometimes you just have to win. Some conflicts just need to run their courses and some bad guys just need killing. Nazi ideology was not discredited UNTIL it was defeated on the battlefield. No amount of peaceful persuasion or appeasement worked. People thought communism was a viable alternative to the free market UNTIL it ignominiously collapsed. Massive economic evidence and even the presence of a very large and deadly wall running down the middle of Berlin did not convince the believers to abandon their failed ideology. Earlier forms of terrorism from the Barbary Pirates to the Bader-Meinhof didn’t go away until they were defeated. We tried appeasement in the 1930s and we tried ignorance in the 1990s. These things did not work.

Ideology is weakened AFTER its defeat. That is often the direction of causality. In our recent case, more people are drawn to be takfiri when being takfiri is easier and more beneficial. People are attracted to success and avoid losers.
