Sickly child or not, Obama and the Left before together aborted the investments towards something better than the ISIS parasites they inevitably spawned.
Which of course is an evil. Nobody says it wasn’t. Sticking directly with Iraq could have allowed a revamp of their government structure that recognized that democracy did not work but a kingdom would, without all this pain.
However God doesn’t let pain happen without any reason at all. Sometimes it is the only thing that can wake us up to the knowledge that there is a problem that needs to be addressed. Standing around blaming is like getting distracted with the alligators when the goal was to drain the swamp.
