"Should"...what is that supposed to mean?
Taiwan is an independent sovereign country. It has never, through-out the islands history, never been a part of mainland China.
As far as mainland China is concerned, Taiwan has merely been a convenient refuge for scoundrels, scalawags, ne'er-do-wells and warlords seeking refuge from the continuous deceits, betrayals and being on the sh!t-list of whatever "king of heaven" inbred that happened to occupy the throne at the time.
If you are going to come on FR and pimp for the PRC/CCP invasion of Taiwan, you might consider that there are some who will dis-agree with such pimpery.
I don't believe anyone, not even in China, are talking invasion. Rather, China is building the economic and political structure, that overtime, will gradually steer Taiwan to be part of China.
I know someone who is from Taiwan. Born and raised in Taiwan. The family are descendants of those who retreated from the Mainland. She and many others, who have roots in Taiwan (but originally from the Mainland), believe that Taiwan is part of China.
The caveat is, that China become a democracy. There will always be a chasm until then. But once China becomes a democracy, I believe Taiwan becoming part of China will be a done deal. And without a shot being fired.
I am not pimping for Taiwan. I’m simply stating what current U.S. policy is. We have adhered to a ONE CHINA policy since the 1970’s in case you haven’t noticed.
I don’t know where you get the idea that I want the PRC to invade Taiwan. I don’t think anybody wants that to happen.
