I think people that think that Taiwan will declare independence are seriously misguided. The DPP is seriously unpopular now: the failure of the recall initiatives, the imprisonment of Ko Wen-je, and the fact that William 赖皮 is a total idiot and stooge (he only won with 40%) all point to this.
Furthermore, Chinese soft power has been rising this year, while America's has been declining. Trump's tariffs are deeply unpopular, and 赖狗's dickriding of the USA and Japan is not helping. So many people in Taiwan scroll Douyin, watch C-Dramas, and buy Chinese shit from Temu. China is getting richer and richer. Beijing and Shanghai's GDP per capita has almost surpassed that of Taiwan. There are numerous individuals like 馆长 engaging in United Front Work, and showing off China's power.
Even though the toads are delusional, they by no means represent all of the Taiwanese. It's only these mentally ill/descendants of Japanese collaborators that truly oppose China. Notice how China's really only been attacking people claiming Taiwan independence, and not the KMT/TPP? I think people are also all disgusted with these sorts of people - especially when you consider how most of them look and act.
Taiwanese people are still Chinese after all; they are pragmatic and smart. When you speak the same language, have the same history, eat the same food, it is easy to identify with the upcoming strongest state in the world. This is especially true among the Indigenous peoples, Hakkas and Waishengren. With time, Chinese identity will re-emerge.
I think peaceful reunification (although with significant coercion as well, as has been the case for a long time) is the most likely, and optimal outcome. It probably would also be a sort of 1C2S, with the DPP being banned to make it more palatable for the remaining Taiwanese that are still on the fence. The only thing we should fear, that could lead to a violent outcome would be a color revolution brought on by the USA, like 1989, Sunflower, Umbrella and 2019 HK. However, I believe that this probability would be low, and even if it did happen, the success rate would be low as well.
