Just not strong enough until bombs and troops starts pouring into Taiwan with American ships become a smoldering wreckage sinking into the South China Sea.
I agree with the premise of your argument as much as I loathed it but I do see the logic of what you have said regarding China's goal and constraints with respect to China's aims and objectives vis-a-vis vis Taiwan which is to prolong or hold off on the armed reunification for as long as possible while building up its huge military to create not only deterrence against America and its allies but also to compel and create an impossible and inevitable scenario for the Taiwanese separatists that Independence is a lost cause.
America's and Europe's goal are to keep on needling China's red line until all the red lines all but vanished and goad China in untenable position where the only viable option is for China to activate armed reunification no different to the Russian decision to invade Ukraine circa 2022. All fine and dandy since the American and western prognostication is that the outcome of such a war with China will favor the west judging from the way and perceived Russian ineptitude and incompetence in their war against Ukraine without direct U.S. involvement, a war with China over Taiwan that guarantees US allied direct participation gives the impression that China despite it's fast pace military development, procurement, and the manpower it possess is nothing but a paper tiger with anemic or next to nothing experience compared to the supposed decades and institutional advantages US military possess.
Such arrogant assumptions and gross underestimation of China's military not to mention it's MORALE AND WILL TO PREVENT THE REPEAT OF 100 YEARS OF HUMILIATION along with all of civilization struggle against U.S. led alliance and Taiwan are factors that no American idiots have taken to fully understand or appreciate. The American way of war will have to be upended and must be revised if it stupidly assumes that a war over Taiwan is going to be limited to within China's periphery.
He's right that it's in the Chinese best interests to wait as much as possible for the armed reunification with Taiwan, like until 2050, as China is today objectively growing way more than the Collective West in every way imaginable, tech, economy, military, diplomacy, you name it.
However, I personally think that he is wrong in his assessment that China could actually successfully hold for that long with all those kinds of provocations happening constantly. I mean just out of domestic reactions to those provocations, from inside China, the government would need to do something in return to appease the increasingly confident population of their country for legitimacy.
And as US + vassals provocations rise, in the future, the people inside China would also demand sharper reactions from the government too as the previous reactions failed to deter. It will be like a cycle from which you can't break out. Hence, I see no way for that conflict to be successfully avoided until 2050. I think the US is preparing for 2027 judging by their rhetoric and they will do everything in their power for that to happen. The chances of them defending Taiwan or stopping China's rise in 2050 are 0%, but today, they are still something. They think that if they successfully defeat China and get a favorable outcome from the Taiwan scenario, China's otherworldly rise would stop.
Anyway back to @tamsen, I think he also underestimated the Chinese chances of success, even right now, that's why he thinks that China could successfully hold on until that point. I think it's way more in Chinese favor to win even now, not to mention in 2027. I'm talking about a 70-90% potential win rate in 2027 in my opinion.
I base that assumption on the fact that NATO failed to militarily outproduce Russia despite them having 30 times smaller nominal GDP and the nominal GDP the size of Italy. I see no possible scenario in which they could outproduce China, the factory of the world. Not to mention that it is a stretch to assume that the whole of NATO would support the US. And that is the most important thing as the US weapons stock would run out in a few weeks. The wars today are still won by industrial might, not to mention Chinese overall morale which would be seen as defending its 23rd province 100km from their shores, against US morale of going against another superpower 10000km from its shores in the 21st century.
