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?
No. NK has a bunch of artillery hidden in the forested mountains just north of the border. And and SK has a lot of population centers within within firing distance. And this includes rockets/missiles with some rather spicy warheads.
And rough terrain ensures that a quick blitz to topple the government and their nuclear arsenal won’t work.
Sure, NK will not be able to hold off SK in the long run, especially if SK invites friends. But Seoul will be leveled.
Plus, China really does not want a US ally on its border, and are likely to intervene.
No.
Starting a war is astonishing unwise.
Also, what will happen with South Korea’s strongest military ally (the US) in less than a month?
