I hope you don't take this the wrong way, but nothing about what you said about progressives is related to the discussion/issues about us being in the Middle East, at least from the way you've written.
I was speaking about institutional change as about what is going on in the Middle East with America involved, drone strikes, war etc. I'm not seeing what more taxation, M4A, or progressive politics has to do with closing Guan Bay, getting us out of the Middle East conflict, and the general issue with American presidents being war criminals, honestly. Like, it really isn't as simple as just "okay we'll pull out all troops and just leave them alone," even if we wish it could be like that. Even if in the US there was magically no more being beholden to corporations profiting off war, we still have to consider what it means to do that. Right now, the question of how we'll get the US to be less beholden to corporations profiting off war still stands. Taxing rich people more so we have better healthcare doesn't make those defense and military corporations any less likely to exist, which, from what I understand, is part of the reason why there's so little incentive to push to remove us from these wars.
