I was just reading about this the other day: Like Bernie wants to stop resourcing Israel, some US politicians had a condition that Azov would not be assisted. But apparently the Pentagon got that overruled
I think that was way before Israel's current massacres. Congress banned providing direct support to Azov in 2015 and then unbanned direct support in 2016 under pressure from the Pentagon. There might have been another attempted ban after that, I don't remember. Even when the ban was in place it's not like it was hard to get around, they just had the Azov guys join a different battalion for the duration of the training (and wear long sleeves).
Wow, that is super fucked up. I hope somebody overthrows the Shah.
