China borders North Korea, they'd see a massive influx of refugees if we were to strike. Besides that yes it is seemingly true that china has oil and other deals with north korea and russia. Between the queensway 88 and rosneft. Whereby Exxon and Rosneft are poised to do deals through king and spalding our new fbi directors last gig. I think russia's oil industry benefits greatly from the regional threat. Allowing russian headway in syria and possibly qatar. Futher decreasing American access to minerals in the south china sea also. While threatening both guam and hawaii as duterte in the philipines blocks access to coconuts a commodity Americans greatly desire however the pharmacuetical industry doesn't want us to have. Trump and blackwater seemingly want a war. Exxon just wants sanctions lifted so they'll pretend russia isn't backing north korea. I wonder how it will all play out
