discusses some of that history back to the 1970s. It has gone on far longer than that.
Both the US and UK governments are aware of where their weapons are destined for, both pretend to have no knowledge or control.
It's exactly embracing the notion that five eyes track the volumes of their arms sales and are indiffeent to their arms being used to kill children, civilians, etc. as long as they're not being stockpiled for use against the originating nation in any significant volume.
I'd suggest that Russia is less adept here than the US or the UK if they're being harmed by thir own supply.
