why is he so intent upon telling the enemy what he would and would not do?
Try to think like 0bama ...
Who are his friends? Who are his enemies?

Your idea of "the enemy" and 0bama's idea of "the enemy" may be very different.
Shy? He's a Muslim. Sure, Muslims fight, but they also support each other, the further away, the more the support.
He's hoping they'll get the message and not do anything too inflammatory--like beheading Americans, or trapping 50,000 Yezidis on a mountain-top and, without intervention, either killing or enslaving them. If they lay low, and show they can be a responsible addition to the 57 Muslim states, maybe we can start up trade relations with them. /S
