Not sure what point you're trying to make?! NATO may have been involved in Syria, but as you say, NATO had no involvement for "the past year". I'm not sure why that is?? Was Turkey making noise about invading Syria back then? The EU has more skin in the game than the US when it comes to killing ISIS and ME terrorists, so why did NATO leave Syria?
Funny how that goes, and the reason is also fairly clear - you plainly don't understand anything that runs counter to your whiny, mendacious narrative.
In that infamous prison camp in Iraq, Camp Bucca, after Bush's criminal war of aggression, that brought together the remnants of Saddam's military and Islamists, combining military expertise and religious fanaticism, AQI emerged and infested Iraq, then moved to Syria while it morphed into Da'esh. That monster is the creation of the U.S., and what's needed now is the U.S. cleaning up the mess it created, like grown-ups do. President Obama did a reasonably good job, using minimal means, joining up with the Kurds who took the bulk of the casualties and did all of the on-the-ground fighting. Whereas the Trumpy cuts and runs, with your support, leaving the Kurds exposed to the Turkish army but also to al-Nusra-style monsters Turkey cultivated, while Trump is in effect indignant others aren't changing his diapers fast enough.
All you have is your whining about why, oh why, others aren't cleaning up the mess the U.S. created. And why, oh why, poor, widdle U.S. is being taken advantage of, and exploited. Now, whine along.
