US didn't collapse after Vietnam, why would they collapse now. People who are politically powerless hope for catastrophe but the left in most countries no longer have the mass base and political power to do anything when the opportunity presents itself. There is a lot of work to be done.
Well yeah, but you gotta start somewhere, and I think we have the wind at our back in the moment. The greatest tool the oppressor has is to convince you to give up and there is no hope because then you defeat yourself. The least you can do is make them have to actively defeat you and sometimes simply living as a descent human being and educating those around you is resistance enough. Not everyone is a Lenin or a Mao, Communism is built through the labors of millions being the best people they can and standing up when they can.
I'm sorry for coming off as if I'm being a doomer or saying don't do anything. I'm saying the desire for total collapse when there's no party or movement (whatever your tendency) capable of taking advantage of the chaos is putting the cart before the horse.
