We kill a bad guy and Iran puts on a fireworks display with really cool rocket trails but no personal injuries.
Now, if our President is half as smart is as smart I think he is (door open for Dee or Palin to take that one to the bank), he will make a public speech saying we don't want things to escalate. We want to be at peace with everyone but must stand our ground in the face of atrocities.
Iran can tuck their tails and say, "well at least we fired back, Allah be praised". They will still sponsor terror nests all over the world who will take shots at small targets but then they can say, it's not our fault.
Trump you have a chance to be the bad ass but to also be a calm, rational diplomat. Give it some thought.
