We DO have a clear enemy. It's just we can't locate him. Different concepts. Terrorism is our enemy. And, as your President has so correctly stated, terrorists are the ones who harbor them. I would put in the same bag the ones that vocally support terrorists or harboring countries.
As ygsmilo states, key point on this issue is money. They need it as bad as we do, maybe even more. Interdiction on assets belonging to suspicious people (individuals, corporations countries) I think it's in due order. And, as long as this will not cost immediate lives, I would start with this, on a "first shoot, then ask" basis.
