Yeah, I’ve heard about the Green Beret “advisors”. Generally what they do is train, rather than engage.
As far as your long term view of foreign troops in Syria, I don’t disagree. As long as the Syrians continue to choose their elected leaders AND other countries aren’t invited into a sovereign nation looking to protect it’s interests.
What we’ve had for years is foreign interests trying to overthrow a duly elected gov’t. in a sovereign nation. Not Kosher.
