I’d have no problem with the Russkies arming the Irish to attack Britain and get them out of occupied Ireland
The Soviets were financing (partly), arming and training the IRA, using Libya as their cutout and training ground. Weapons were mostly from the US because it was easier. They also got the IRA to attack the BAOR (British Army of the Rhine, the British NATO component), in Germany.
So there is good reason for the British to be a bit sour vs the Russians.
My friends in the UDA haven’t left NI. Good luck with that.
