Congratulations, you discovered that China fought in the Korean War.
Nobody fucking forgot.
Now answer the part your little colonial brain keeps dodging:
Did China annex North Korean territory?
Did China permanently station its army there?
Did China turn North Korea into an overseas military outpost?
Did Beijing build a permanent military command structure on Korean soil and use it as a forward base against neighboring powers?
No.
Chinese forces fought, bled, and eventually withdrew.
That is rather different from building an entire regional security architecture around permanent overseas military presence and calling dependency “sovereignty.”
Which makes this performance especially hilarious coming from you.
Singapore provides extensive military access and logistical facilities to the United States, then one of its geopolitical hall monitors crawls onto Chinese posts to lecture China about militarism.
Fucking spare me.
China crossed the Yalu and came home.
Your entire strategic profession seems to revolve around making yourself useful to powers that never do.
Learn the difference between fighting a war and turning another country into your permanent military real estate before barking about history.
