I might miss something about "Russia’s desperate need for military drones and asking for China's help." Can you show me the source? As for "Kim doesn’t trust China," well another source to prove it is well appreciated. For a leader (Kim) took China's airplane to meet Trump in Singapore is not a small matter. In fact, it's a very serious one.China will militarily intervene on behalf of North Korea if its first attacked by US/South Korea. That’s the extent the defense treaty. Deep down Kim doesn’t trust China.
——-In fact there is a chance that SK with backing from US might take advantage of a Taiwan war to attack NK. Create a two prone war for China. India might do the same along the sino-Indian border—-
Outside of that scenario, the only reason North Korea might attack Japan (and that’s a huge if), is If the regime is facing existential threat Japan/US. It’s not going to Nuke Japan to help China over Taiwan.
A true leader doesn't need to ask for his friend's help to safeguard his country. He knows his friend will come when the time is right - all agreements are done behind closed door. On the contrary, Europe has opportunists as leaders. One of them even cried to save her plush cushion.
The three leaders of Russia, China and North Korea are well aware that one of their country falls, means all will fall. They try their best to tame an angry savage on the way down to hell with minimal impact as much as possible to the whole world.
Forget about Japan and South Korea, though their leaders seem ignorant, they are far from stupid. They'll use what has been taught to them by their big neighbor - barbarians against barbarians. Then once things settle down, Korea will be one and in peace without war. But if things turn sour, Kim knows what to do.
My oh my..... Reading too many western MSM and believing all the eloquence-yet-verbose rhetoric makes one brain hollow.....
