What is a winning strategy for defeating ISIS?

A B-52 loaded with B-61s/83s... Sorry, I don't see another good answer...

I suppose that is an easy challenge, Sir, because it obvious that no single person on this website will have an appropriate and rigorous strategy that details our success over ISIS. Although, I do not doubt there will be many good ideas. Does that change the fact that Obama still doesn't have a strategy? It does not. The question then becomes, is anyone with the necessary experience and position suggesting a new one? I do not have this answer. I'd be interested to know. I enjoyed reading the answers your question provoked. v/r - R. C.

Stop supplying them with weapons by proxy. Get the Iraqis to commit to the fight. Possibly some limited direct engagement ourselves.
