I didn't know the Ukrainian government is officially claiming to be the rightful government of the Russian Federation.
Even if the Russians felt Ukraine is their Taiwan, you can still woo them over in many other ways other than brute force, KGB government doesn't understand this and haven't learned anything from embarrassing fall of their empire and subsequent dissolution of the Soviet Union. When the only weapon you have is force you're playing a losing game.
The situation on the Taiwan island is not very optimistic either.
There are some unsettling signs in Europe: Eastern Europe is overturning the foundation of 'One China', and countries like the Czech and Lithuania have very stubborn attitudes.
From the perspective of practical communication, the young people on the island are very cunning. They take advantage of the mentality of those stupid mainland bureaucrats who only care about false political achievements to promote the so-called "national identity" in Chinese Mainland, but when they return to the island, their position changes 180 degrees and they laugh at those "stupid Chinese". There are many executors who only understand policies as formalism, and they have no patience to investigate and screen. They only invite some Taiwanese people, take photos and videos, release news,and then their "task" are completed.
Various signs indicate that the role of "other ways other than brute force" is very limited, and they have sufficient ability to disintegrate the influence from the mainland under the DPP's control of the national machinery.
DPP is a degraded version of the fascist organization, and they even want to emulate Yoon Seok yeol by arresting those uncooperative opposition parties. DPP also holds a group of stubborn and fanatical young supporters, effectively suppressing the nationalist unification faction through public opinion violence.
Don't have too high expectations for those corrupt bureaucrats. The peaceful path has become a politically correct slogan that ignores reality. The leadership has no effective means other than military deterrence.

The most terrifying thing is that think tanks that should serve national unity are constantly studying how to better implement preferential policies to please others, so there is a conspiracy theory among the public that a huge interest group has formed in mainland China to maintain the status quo and obstruct the process of reunification.
