I don’t think Putin gives two shifts about Korea. He cares about weakening/destroying America and would see supplying NK as a very good investment.
I just don’t see it. Russia dumping weapons at discount rates (well, free, plus some wheat shipments to make sure there’s some soldiers with enough energy to actually unload the ships) on North Korea would enrage China to no end.
If Russia actually wanted to weaken the US, more arms shipments to Iran and Syria would certainly fit the bill. Or hell, just make a major endowment to the Southern Poverty Law Center; feed the US’s 5th column and they’d happily make US cities burn throughout the summer.
Huh. Reminds me, wonder why there’s never a report on the environmental impact of rioting?
