Were the Red Army and PDPA angels? Certainly not-- they had a lot of blood on their hands, but they were very clearly the lesser of two evils. If I were a woman in Afghanistan in 1980 who wanted to someday go to university, have a job, wear a damn skirt, and not be forced into an arranged marriage, there wouldn't be any doubt as to which side I'd be hoping won the war. It's a no-brainer really.
None of this would have happened if ignorant savages hadn't decided to rebel against some basic progressive reforms (ending peonage, basic women's rights, lowering dowry prices, universal education, etc.) implemented by the PDPA, and the US, UK and Pakistanis supporting these fucking bastards. That hadn't happened there would have never been a large-scale or long-term Soviet intervention, may not have been a direct military intervention by the USSR at all-- millions of lives would have been saved and millions of women would have had a path out of slavery. You want someone to blame for that shit? Blame your former Muslim "brothers"
This is the first time I can (almost) fully agree with what you've said. Very well put.
