I have very little confidence in the US left to reverse this trend

Oh we absolutely won't. The trillions of dollars of weapons the state has stockpiled will either be used in an external war or an internal violent suppression of dissent, maybe both, but one way or another they're getting used. But with things trending the way they are now, I think that conflict will likely shake the empire apart.

With a lot of luck, the experience of living through it will also finally be enough to galvanize a tangible domestic socialist movement.
