One of the things we're sorely missing in the anglo sphere is any actually progressive candidates.
Not to be pedantic but you're conflating two issues: being anti-war and being pro-troop presence. One of the big reasons the US has kept a troop presence in the middle east is to deal with the human cost of the instability that was created in the 2000s by those wars of choice.
I can't speak for all progressives but those that I know have both anti-war views (stop shit-stirring with Iran) and pro-troop presence (try to stabilize the region before withdrawal). I will admit that both have been going very poorly lately.

The remaining troops were there in an advisory capacity. And Trump has been trying to pull out those advisors.
The needle has been pretty steadily moving for the last 10 years, it's just been slow going. It's also debatable if the number of troops there should ever be zero if they're only acting as advisors.
Take for example the anti-war stance. As far as I know Trump is the only one continually advocating for a troop withdrawal in the Middle East. This used to be a solid progressive issue.
