News coverage of China is asinine, vacillating between the WSJ/Gordon Chang “the communists are about to collapse” nonsense and the “General <x> says the Chinese are aggressively aggressive and catching up” patter. The chip bullshit is all about Intel lobbying for billions to pull its nuts out of the fire.
IMO Chinese policy is methodical and not unlike what the RAND people cooked up in the 1960s. They make investments in Africa and Latin America that benefit China, build up a military power as deterrence, and have a trade relationship with the US and Europe that transformed the nation from a decrepit backwater into a global power in 50 years.
Why would they want a pyrrhic victory (or defeat that would damage the Beijing government) in Taiwan? Taiwan isn’t Hong Kong. Aggressive rhetoric and policy accomplishes political objectives, and the long game is to foment instability in Taiwan and wait it out.
The risk of conflict with China is North Korea and Japan, not Taiwan.
They made a seemingly knee-jerk policy decision after the Japanese nuclear disaster.
The risk of this happening in a US-China conflict is moderately high. Chinese red lines are vaguely drawn. US red lines are more firmly drawn, but the US government system has multiple loci of power, and China seems to have a poor read on US policy as a result. De-escalation on both sides looks rather difficult to pull off, especially because China has a tendency to do things like through hissy fits whenever it feels slighted and shut down existing mechanisms to help de-escalate.
Another way a war can break it is something like WW2 or the Russian invasion of Ukraine, where you declare a war because you think you have a window of opportunity for victory. And if you guess wrong, well, you can ask Nazi Germany how well that works out for them.
Economic arguments for war being irrational and therefore unlikely have a history of falling flat on their face. Most infamously, this claim was made about major wars in Europe right before the First World War: https://en.wikipedia.org/wiki/The_Great_Illusion
