Honest question- has it worked?
Define "worked".
There hasn't been another large terrorist attack on US soil since we provided them more convenient targets close to home.
There is usually a significant dip in effective offensive actions by Islamic extremists in the region after we do one of these ops. That dip in activity can last for a year or more.
The terrorists we kill never commit another attack.
Oil exports from Eastern Syria and northwestern Iraq normally increase after these operations due to a safer transportation environment.
To say the strategy definitively works or does not you would have to know the goal of US policy in the Mideast, and that is notoriously hard to pin down.
But for clarity, I was only pointing out that hitting milita targets in Syria and Iraq was not an escalation of US military operations in the region, not claiming it was great foreign policy.
