I would bet some money before anything happens. Taiwan will disassociate itself from Trump pretty fast. Playing the tough man is easy if there is the entire Pacific between one and the place of interest.
Even Taiwan considers an invasion of China as not stoppable.
I wouldn't trying to go that route. Even if you love your China is a paper tiger posts.
In the space of a day though? Please. Like I said, their entire arms purchases and military doctrine for almost 30+ years has been defense of the island and prevention of invasion until US forces arrive. They will not fall as quick as you think.
Also, it is crazy how so many have such a hatred for Trump, they prefer China and the unreasonableness of their demands for the past 40 years and their actions. China is not a rational state actor. This is still a government that tortures people like Falun Gong, quashes dissent with secret police who take away people in the night and their family, who have issues with almost every single neighbor, are literally stealing land in the south china sea to build military installations, they destroyed a satellite in space causing more space debris in one event than the last 20 years of Russian and US space launches just to show they could, they as a nation manipulate currency to decrease the cost of their exports and flood nations with their goods causing millions of jobs to suffer, they control media through extensive use of propaganda etc.
The fact that this rattles China so much should tell you how rational they also are. Fuck Donald Trump, he is a clown and a bad businessman. But he is doing exactly what he said he would. Rankle China. The fact that they get rankled should make China worry. In the world, the US is still the unquestioned economic and military power.
Will the US risk war over Taiwan?
They are legally bound to do so. The question would be the same for NATO nations. Would the US risk war for Poland if Russia invades. If the US won't or doesn't, than all they have ever said of defense of allies, democracy, will go out the window if they allow communist china to invade Taiwan. The US would not prefer it. The world would not prefer war. But if it happens, it happens and then China will realize do they want to go to war with the US for Taiwan? Also you have to ask, will Taiwan risk what they have for war with China.
