If America Invades North Korea Again, the Prerequisites for China Not Entering the War (Please Let This Through)
I believe that if America invades North Korea again, China can choose not to enter the war, but only if the following prerequisites are simultaneously met:
One: America must understand that the Korean issue is different from other issues. Countless Chinese lives were shed at the 38th parallel. Any attempt to cross the 38th parallel without the consent of the Chinese people will be considered an aggression against China.
Since the 38th parallel is essentially an armistice line, in a certain sense, the war has never ended. Therefore, any act of actively crossing the 38th parallel can be seen as a continuation of the war. Of course, positions can shift in the course of fighting, just like in the Romance of the Three Kingdoms. If the interests are sufficient, China can even stand on America's side. But any attempt to cross the 38th parallel without the consent of the Chinese people will be considered an aggression against China. To cross the 38th parallel, corresponding interests must be given to China—otherwise, no deal. Anyone who disrespects the blood of countless Chinese shed at the 38th parallel will absolutely not be respected by the Chinese people. You want to cross? Fine, but you must pay the toll.
Two: America must unconditionally support China's unification with Taiwan.
Some might say these are two separate issues. But in this world, nothing is truly separate. From the standpoint of China's national interests, this is one issue—an exchange of bargaining chips. Sometimes you have to know how to muddy the waters. Regardless of political faction, when participating in international competition, China must have its own voice and must fight for its own interests. If the Chinese side can't even accomplish this, getting led around by the nose all day, then what kind of "strong nation" is it? If previous matters were still far from China, on the North Korea issue, China, as an influential party, must seek the realization of its own interests here. Therefore, the Taiwan issue must be linked with the North Korea issue.
Historically, these two issues have always been connected. If not for that Korean War in history, Taiwan might have long ceased to be an issue. From a geopolitical perspective, these two places are precisely China's two outward-facing contact points. At least one must be maintained, otherwise China gets suffocated. From this angle, China must absolutely use the North Korea issue to muddy the waters and profit from it, and must clearly and firmly tell America: North Korea and Taiwan—you can only control one. If you mess with North Korea, we will take Taiwan.
Three: America absolutely must not have any accidental bombings or produce major environmental impacts during the war.
That is, America absolutely must not have accidental bombings or produce major environmental impacts during the war. Since Korea is so close to China, and in Iraq, Iran was hit by several bombs for no reason, and the Chinese people do not have the habit of being bombed—once so-called accidental bombing occurs, it can only be regarded as a provocation and must be met with retaliation. So if America wants China not to get involved, there must be no accidental bombings. Furthermore, since American bombs are all dirty, with radiation this and radiation that, and since strong earthquakes have occurred after every American war, should such natural environmental changes caused by American war occur, America should provide adequate compensation to China.
Four: China has the right to supply weapons to North Korea.
There's nothing much to say about this. Market economy—if North Korea has the money, or if China has some weapons that are expired and too costly to destroy or store, China can supply weapons to North Korea at its own discretion.
Five: Post-war, all of China's economic and political interests in the new Korea must be guaranteed.
There's nothing much to say about this either. China's historical influence over Korea—America should not be unaware of this. So let's continue maintaining tradition. The Chinese call themselves lovers of tradition, so this tradition must be upheld.
Six: China must participate in post-war peacekeeping. American troops must have a short-timeline for complete withdrawal from Korea after the war, and Japan must significantly reduce its current military spending, with US forces stationed in Japan also gradually reduced.
The presence of American troops would have no justification with Korean unification. And Japan has been secretly increasing its military capabilities, using the Korea issue as a pretext (though everyone knows that's not really the reason, but many things should be played dumb). Once the Korea issue is resolved, there would be justification for suppressing Japan.
In short, I believe that in the game between nations, you cannot always play by others' rules. China must have its own voice. Especially on the Korea issue, China absolutely must not back down. America can invade North Korea again, and China can choose not to enter the war, but the above prerequisites must all be met simultaneously. On the Korea issue, China must not only take action but should exert every effort to win the maximum benefit.
