I think anyway one reads this document, the US capitulated to Turkey's demands+thus Erdogan secured a major strategic victory, which will allow Turkish army more leeway on ground. However a quick look shows the document is not worth paper its written on, with many unclear goals.

So let's break this down. I think obvious point is it gives zero recognition to YPG, or Kurds. This document pretty much equates the YPG as being terrorists, a Turkish claim, and one that most in US Congress are clearly arguing against. This in itself is a HUGE Turkish gain.

Further, Turkey received US recognition of its right to protect its border by occupying a foreign country. Of course this is NOT internationally binding-but this is nothing to brush aside. The US supports Turkish occupation of Northern Syria--a safe zone, Turkey has long sought.
