Enemy of thy enemy.
We protect Korea from the Kims. We also buy from them and treat them with dignity. Break those pillars and yes, China controls Asia and the Pacific in a way Yamamoto could have only dreamed of.
> and the war is mostly a defensive one for China
China holding Taiwan is a direct threat to the security of Seoul.
Some enemies are more beneficial to left unattended. Realistically, there are almost no scenarios in which it would be advantageous for Korea to enter a war against China.
> We protect Korea from the Kims. We also buy from them and treat them with dignity
Still not worth a war with China.
> Break those pillars and yes, China controls Asia and the Pacific
Still not worth changing sides to China
Correct. This is where having America in the theatre, and in particular Taiwan, benefits Seoul.
Sort of like how Poland benefits from Putin being bogged down in Russia.
