I'm not saying it's simplistic at all. I said "it's not unreasonable to think.... " specifically because the one thing I'm sure about is that none of us really have any idea what is going on amongst different groups and what portion of the truth our government is telling us. It's hard enough to get an accurate news story reported on something that happens down the street. I don't believe we get even close to an accurate picture of what is happening in a culture very different from ours, and how we affect it.
The idea that we are going to just bomb our way out of it without creating bigger problems seems rather optimistic.
Such as? Syria and Iraq are both already hellholes that would be better off with Assad in charge of all of Syria and Saddam in control of Iraq. That ship has sailed. It appears that many of these ISIS "fighters" are cowardly thugs who have come from all over the world to be violent animals. That is why many of them have returned home. Seeing JDAMs dropped on their buddies won't help the cause of ISIS either. We could take out ISIS, but power vacuums in Iraq and Syria will be as wide open as they were with and before ISIS. So no real change, only thing we risk is losing aircraft and crew. I certainly don't want to lose any of our pilots, however I don't feel any sympathy for these ISIS vermin. Maybe just maybe, it will teach them that facing a western military is whole different animal than the Syrian and Iraqi armies.
