Potential War in the Middle East

The U.S. military seems to be taking a very long time to finish off ISIS/Daesch in Syria. Is Turkey still trying to attack Kurds in Syria. I assume Russia still has some troops in Syria. Assad, of course, still has his military in Syria. Apparently Iran has some forces in Syria. Israel claims Iran has been building up and working with Hezbollah to prepare an attack on Israel from Syria. Israel has been shooting missiles into Syria to destroy (what it claims are) Iranian military sites.

The common denominator is that there are a lot of military forces in Syria, though each military isn't directly attacking each other military force.

Could that change?

If America is still in Syria because Donald Trump wants to spark a huge war with a Tonkin Gulf kind of event, then anyone working there who isn't interested in participating in that kind of melee should probably leave. But, what if anyone attacks U.S. forces? Would Turkey answer the NATO call to protect U.S. forces against Iranian or any other military forces?

It's time for everyone to leave Syria, return home, sort out exactly how evil Vladimir Putin, Donald Trump, Bibi Netanyahu, and some others have become.
