There are some misguided religionists convinced of the political advent and supremacy of their views. They play on various issues to get popular support, which they lack, except on general issues, like an anti-American sentiment and distaste for their own political alternatives.
There is no "war" (except in their mind) and that is absolutely the wrong word. We ought to take greater care with that, lest we inadvertently frighten ourselves into hastening what we hope to forestall.
And ... there is plenty that "we" can do, including patience, learning, and understanding - all of which prevent the kind of broad brushing of "Islam".
