Actually, publicly revealing when, how and where the United States (and some allies) will likely strike makes sense, given what Obama wants to accomplish. If his goal were to fully enter the Syrian civil war and decisively end it, then, yes, secrecy would be the way to go. But the administration has been very clear that it has a much more modest goal: to punish Syrian leader Bashar al-Assad for his suspected use of chemical weapons so that he, and future military leaders, won’t do it again. …

If the U.S. military just fired off a bunch of missiles, it would probably cause more civilian causalities than with its current approach, and the amount of damage it caused would be tougher to predict. Maybe it causes less damage than the United States wants, and then Assad is not sufficiently deterred from future chemical weapons use. Maybe it causes more damage, and then Assad might feel compelled to respond, perhaps by striking Israel, and that’s how things spiral out of control.
