Well, since the OP was about how to deal with ISIS, "breaking" them in the sense that Germany and Japan were seems to be a desirable result.
ISIS is an idea. It's not a particular ethnic group or population of a particular piece of land. Ideas are notoriously hard to repress successfully.
Here's my op-ed that uses long-term orientation, probabilistic thinking, numeracy, consider the alternative, reaching our actual goals, avoiding intuitive emotional reactions and attention bias, and other rationality techniques to suggest more rational responses to the Paris attacks and the ISIS threat. It's published in the Sunday edition of The Plain Dealer, a major newspaper (16th in the US). This is part of my broader project, Intentional Insights, of conveying rational thinking, including about politics, to a broad audience to raise the sanity waterline.
