Maybe back in the 70s. I have KMT friends who openly say that there’s no likelihood of unification with mainland China. For the most part they like the status quo, they love their Chinese cultural heritage, and don’t really care that it’s confusing for the rest of the world as to whether they are Taiwan or ROC.

The reason that ROC still de jure claims 20th century territory (including Mongolia) is because redrawing the borders would upset the status quo and signal independence to PRC which is a red line for missile attack. In every practical way, the Taiwan province has been streamlined away and the ROC _is_ Taiwan.

KMT certainly for a time nursed hopes that eventually they will "retake" mainland, atleast during the time that CKS was in control.

CKS looked down on the possibility of "settling" for Taiwan alone.

Subsequent ROC/Taiwanese governments have not renounced that line of thinking. Even DPP officialy endorses "Status Quo".

Taiwan is split politically on the issue of whether or not it is a part of China or a unique independent nation.

It is also a status quo not really worth rattling at the moment, since all indications are that when Taiwan changes its mind the PRC will start treating it like a breakaway province and start the invasion.

That’s not what GP means. He means they consider themselves to be the “true” China and the “true” ruling faction of China.

That's not what I mean. The political party that won the last 2 elections, DPP, disagrees with both of your points. They believe the Taiwan government is "true" Taiwan and People's Republic of China is "true" China, and their is no overlap because Taiwan and China are separate, independent nation-states. It's the minority party, KMT, that maintains, along with the PRC, that Mainland China and Taiwan are inseparable constituents of the same "Chinese motherland."
