Also, bomb the ever-loving shit out of South Korea like we prepared to do.
Defend the DPRK
Contact Russia, secure arms for a protracted people's war through Vladivostok and the Russo-Korean border there. Go to the UN and request a humanitarian ceasefire so time can be garnered for a Tet Offensive.esque maneuver. Recruit fighting Koreans from the refugee camps in Manchuria.
Level Seoul, use the tunnels to invade when finished.
Also request China assist us with a good chunk of their military power on the provision we slap a DPRK flag on all of it and it remains under their control.
Help our comrades in the south to rise up in guerilla war under the banner or the Anti-Imperialist National Democratic Front.
Fucken wot?
You launch several propaganda campaigns in south Korea through sympathizers. Several hundred thousand go on protests against the war, while a group of a few hundred militia travel to japan and commit terrorist attacks against the local government.
China gives you two hundred thousand guns and several planes, tanks and boats.
You set up defensive positions near the Russian border, building bunkers in the mountains. You funnel useful civilians, such as scientists and engineers, into several villages hidden in valleys and under cover from trees. Your remanding military is sent into these mountain strongholds and you begin to prepare. The US forces reach the Chinese border in the far west, and most remaining towns are captured. You contact the UN, and request a ceasefire, but the USA ignores the demands from the UN
No, it's become 1984 in real life at this point due to the social credit schemes and surveillance. "Socialism with Chinese characteristics" is the main economic model. They support you only because they view you as a buffer state.
Just to see how much of a complete shitstorm can they create.
Koreans fucking hate Japan for a long history of grievances
There was a shitstorm in the last few weeks because SK military locked on to Japanese aircraft and simulated AA launches
Rebase our criminal and smuggling organizations to corrupt countries which won't bat an eye. Make smuggling everything and anything from drugs, to people, to conventional, nuclear, biological, chemical weapons into the USA. Team up with, smuggle in, and supply Wahhabists. We've got subs and a fleet of commercial stuff to do it with.
Give them to the peoples' war guys. Attempt to stoke US-PRC tensions on the Korea-China border.
