Interesting post. Funny to think that the Commander-in-chief of this operation is a Democrat too.I'll just leave this here, because I think people forget: Google "operation inherent resolve" and take a look at CENTCOM's operation status.
The Combined Forces in the Syria/Iraq theater (of which the United States is by far the largest participant) have released nearly 50k weapons, over some 27k combat sorties. It has cost the United States $7.5 billion so far. You can see the battle estimates of how much damage has been done.
If you are going to argue with strangers on the Internet about American foreign policy, by all means, have fun. But let's not forget that the United States is engaged in actively bombing territory held by IS, every day, and is killing a lot of people. Hundreds, on some days. And that the Syrian government is engaged in far more indiscriminate bombing across much of its former territory.
That's the reality of what the US (and its allies) are doing against IS. The air war could be intensified, but you can be certain that would cause even more dislocation of the population and a larger wave of refugees into Jordan, Syria, Turkey, and southern Iraq. The propaganda campaign waged by ISIS, which has caught the imagination of a couple violent losers, is really not the main story.
