They’re creating supply chains. Putin would love to supply NK with weapons and supplies to use against us. That’s partly why we need a WW3 like mentality if we’re going to go down this path. If the world won’t rally with us against NK and Iran and whoever else is aligned with them, we should consider other options IMO.
A united Korea has a heck of a lot more value to Putin than Lil Kim & The Rock(ettes). Besides, Putin wants to sell weapons, not hand them out as welfare.
