I don't see the Syrian decision as folly at all. Trump looked at the reality of the situation over there and made a good decision. What benefit has actually come from the USA's attempts to protect and save the world? The Middle East will not change for hundreds of years. Too much inbred tribalism and stupidity.
You do realize that you are advocating abandoning Christians who were not nearly as persecuted pre-2003? Because they have stated the same pretty much, stay until the situation is better stabilized, ISIS is beaten, Turkey is a threat. The articles have been posted in the world news forum. They have gone from a population of 3,000,000 before the Bush administration to less than 1,000,000 now. And, that in lands, Christians lived in for two thousand years.

Same for the ground war and the Kurds who spilled bloid, Christians too, to defeat ISIS who again may never have come about without prior actions.
I will go with Senators Cotton, Ernst, Graham, all 3 vets by the way, Rubio, Sasse, Menendez, Representative Will Hurd and countless others as knowing and understanding the situation vs not knowing anything about is.
Trump declared victory but no victory could have come about without our partners. Sounds like you don't know much about the situation, "tribal", "Muslims"? "Inbred". What a laugher.
