I just wanna reiterate something and sorry for beating a dead horse here, but I find this one particular thing astounding and didn't want how seriously absurd it is to get lost in the snark:
We've been able to observe for quite some time that when help oust someone we don't like in that region so someone else we prefer can be in charge, that someone-we-prefer will eventually become less tolerable than the previous bad guy we ousted. This is nothing new. But at least back then we could celebrate the ousting of our targeted bad guy and push that place to the back burner for a decade, give or take a few years, before things fester to the point that we have to address the new worse guy he helped into power.
In 2013, in Syria, Assad was the bad guy and the rebels were the ones we preferred over bad guy Assad. Fatigued from our long stays in Iraq and Afghanistan, we didn't go full force into this war, but we helped arm the rebels. Assad was not ousted but the rebels managed to become a more formidable force in the region. And many of those rebels are now a little group you might have heard of called ISIS. It took less than a year, and now ISIS is the bad guy already when the rebels were the good guys less than 12 months ago.
Interestingly enough, since Assad wasn't ousted, he's still hanging around in Syria and even though we were working to have him ousted/killed last year, he's now a strong supporter of any efforts we'd like to make in bombing/destroying ISIS.
Summararized: We help good guys fight against bad guy. Discover good guy is really really bad guy. Worse than other bad guy for sure. First bad guy is actually being pretty cool about it and is supportive of our goal to take out worse guys. All within a years time this happens.
In other words, our foreign policy now resembles a bad WWF wrestling plot arch.
