You make it unprofitable to fight it, and you make their ideas of martyrdom worthless.

To effectively fight a group like ISIS you need to go hard after their leaders, and make the group stupid and mistake prone, and make the leadership look like something that people don't want to follow.

At the same time you go hard after their recruiters and funders wherever they are.

When the American's first went after Al Queda they stumbled on an effective strategy, or putting them on the run and making them a reactionary group. You chase them to the ends of the earth and make them so concerned about survival that they can't do anything else.

The American's failed at that strategy because they got complacent about it and let Al Qaeda off of the mat.

If you want to look at the effective destruction of a terrorist group, look at the multi faceted approach to the destruction of the Tamil Tigers.

They were destroyed by a combination of military, economic, psychological warfare and a enhanced propaganda effort.

With ISIS you can't let it fester and inspire the crazies of the world or it will grow and become more aggressive. You can't sit back and hope puppy thoughts will make them go away. You can't hope that the people that are effectively their civilian base and hostages will rise up in the face of brutality and weaken ISIS.
