Nothing is more urgent than a serious, dare I say compassionate, debate as to where we are going at home and abroad. Technicians cannot master revolutions; every great achievement was an idea before it became a reality. Cathedrals cannot be built by those who are paralyzed by doubt or consumed by cynicism. If a society loses the capacity for great conception, it can be administered but not governed.
One theory is that we will make war look so attractive that we undermine the deterrent. That's Never Never Land. What we have now would have been enough to deter Hitler. But we are talking in a different order of reality.

But they have to conquer more and more territory before they can became a geo-strategic, permanent reality. I think a conflict with ISIS - important as it is - is more manageable than a confrontation with Iran.
