The bad news is that while we can balk military Islamic extremism in the short term, the conditions which have given rise to the I.S. seem to persist.
The foundation of a road to success in any endeavor consists of failure learned from. You cannot have excellence unless you are willing to experience failure.
The fear that the West has of its own youth flocking to the IS alone testifies to the truth of the proposition that the I.S. is a kind of rallying point to marginalized and alienated young people. The energy that feeds the I.S. is derived at least in part from Western society.
My point, in summation, is that our Islamic extremist opposition is receiving the best military training possible from us. They are moving up the learning curve. That portends ill for the West as well as it's traditional Middle East allies unless we can overturn the underlying phenomenon.
In the ideal sense or in the practical and realistic sense?
According to the realistic sense, maybe make East Asia first and only with little or no opposition to Russia and little or no anti-terrorist work in the Middle East. This assumes that the best US political leadership we will see from now on is what we have now.
Our inner politics and popular mood are not conducive to the forming and keeping of commitments around the world.
Ideally, I would think that possibly we could work with friends to turn China back from expansion into the Southeast Asia. That way China might turn its eyes to Russia and thereby restrain Russian aggression in Europe.
Ideally, we should, as a second priority, conduct a successful hearts and minds campaign in the Middle East backed up by a solid commitment to the full use of our military for the purpose of controlling environments where needed to that end.
Ideally, we should have strong and effective leaders in Washington to get the public behind the successful execution of their policies.
Of course Putin may make overtures to our East Asian allies before then. He probably sees us as retreating thereby creating a vacuum he can fill.
