An imminent thread calls for an imminent destruction.
Do we know where in Syria where this weapons are? If not nuke the entire ME.
If they're there, I'm betting we know where they are. And I'll bet that area is under surveillance 24/7. It's not like your everyday Joe can do anything with them. They need to be weaponized and loaded into a delivery system. That would never be permitted to occur if we're watching them.
If it's known where they are and that area is being watched, there are reasons why. Main one being that we want to see who shows up to claim them.
I'm awfully glad you're not calling the shots.
