The big QUESTION is...

... will an 'air supremacy alone' strategy of 'willing' coalition nations be enough to permanently blunt the expansion of I.S.I.L. (AKA I.S.I.S., I.S., Islamic State, Cult of Evil. etc.) forces in Iraq and Syria?

Or, will the scourge simply go under-ground requiring a reversion to a good old nineteenth century 'boots on the ground' approach?

Deja Vu anyone?.
