The Nato chief is saying that North Korea is getting access to Russian missile and nuclear technology, in exchange for troops. If this is true, should South Korea launch a preemptive attack on North Korea before these new technologies are properly integrated and utilized?
It kinda can’t, though. ‘South Korea will be leveled’ is basically the worst imaginable outcome, unless you’re saying they’ll nuke the friends SK invites. Realistically, ‘no nukes/missile strikes at other countries’ is probably going to be China’s only requirement for assistance. Which would make it a horrible grueling land war. Which is going to suck with or without Russian ICBMs in NK.
