Do you really think anything short of war will stop him? I don’t. 25 years of diplomacy and sanctions have failed. If you rule out the military then that’s where this ends.
“Do you really think anything short of war will stop him?”

All options on the table. Responses proportional to the offense. War should not be ruled out, but there is much that can be done before resorting to that option.
