I’ma go way out here and predict something (with low confidence) that should be on the policy-makers’ radar:
China takes Taiwan.
Far fetched? Maybe. I recall that when FDR embargoed fuel deliveries to Japan in the summer of 1941, their response was a little thing called “Pearl Harbor.” Yes, the Japanese had been rehearsing such a scenario for years (and not to put too fine a point on it, but China has been rehearsing Taiwan for a long time too, most recently last summer), built it was the sudden imposition of the fuel embargo that brought them to action.
I now remind that the Chinese economy is weak (hardly on the ropes, however) and taking Taiwan achieves several objectives for the mainland leadership.
First: distraction. It does what Adolph (you-know-who) and Hirohito did at the outset of their wars: it puts the home populace in a different mindset, one of nationalistic furor.
Second: it’s a major blow to the US, not only in consumer products (chips) but in military preparedness, as both segments rely on the abundant, and nearly monopolistic output of Taiwan in advanced chip production.
Third: it’s achievable, at least in theory. China is 90 miles from Taiwan. The US is 7,000 miles away. Not that it makes it impossible, just difficult for resupply and support. China has a million man army, a carrier task force has a few thousand marines available and little in the way of “landing” support.
Fourth: it follows China’s already announced retaliation of putting rare earths and other resources (again, chips and chip fabs) necessary for the American economy at even further remove.
Fifth: the cultural realization of “One China” finally becomes reality, a policy slogan that the leadership there has been echoing for decades.
I can see some people in Xi’s government arguing for “now is the time”, since it has been on their radar for years and several leaked sources have pointed to 2027 as a propitious time anyway, when the Chinese Navy will be up to full capacity for such an adventure.
So probably it doesn’t happen - but maybe it does. You think you’ve seen stock gyrations lately? You ain’t seen nothing yet.
