I don't want to give too many details so as to avoid doxing myself. I never left the US and wouldn't have done so if asked, but fundamentally, I don't think that really matters. It's all part of the same machine. It was well before I became anything that could be described as communist, but all that means is that it hit that much harder when I had to come to terms with what I'd been a part of.
Maybe that's the sort of thing you can't ever make up for, but I'll spend the rest of my life trying anyway. If anyone on this site never wants anything to do with me again after having read this, I understand.
Yeah it sucks where I live like 90% of the STEM jobs are military contractors. My sister who's an engineer was struggling to find work and was trying to avoid companies that make bombs. She landed a job at a place she thought mostly just civilian work, only to discover a few months in that no indeed they do some military stuff.
