The KMT is not pro peaceful reunification. There are no reunification party out of all 3 parties vying for power. KMT is at best pro “saying the right things to placate the Mainland so they can maintain the current situation for as long as possible, probably indefinitely if they can” , while making no real efforts to change the anti-Mainland propaganda and education that’s been going for the past few decades.

There are very little internal forces within Taiwan that actively wants reunification. Those who support it are majority an elderly generation who are increasingly dying out. The younger generation, especially the past 15 years, have been educated to believe Taiwan is not Chinese despite speaking/writing Chinese and having all the same traditions. It’s politically correct there to despise the Mainland despite watching Mainland TV shows and pop culture, and engaging in Mainland’s social media.

Of course the PRC leadership knows that there are no political faction in Taiwan that will move toward reunification. They also understand that Taiwan’s so called independence exist only due to US keeping it as a chesspiece to poke PRC whenever it likes. So they will exert some pressure but mostly leave Taiwan alone for now (unless they do something unbearably provocative) but will prepare to fight if necessary to push US power out of the South China Sea. Once that’s done, Taiwan will have no ability to maintain its separation and will fall into the orbit whether it wants to or not.
