For context: the DPP is the pro-indpendence ultranationalist party founded by local landed elites who collaborated with the Japanese empire during wwii. To this day many Taiwanese ultranationalists around the DPP deny Japanese atrocities such as Nanjing and Unit 731. This may not be the most reliable source, three pinocchios!
There’s no valid argument for Taiwan’s independence as a Chinese settler colony. As proof, the entire DPP argument depends on Chinese settlers pulling a Liz Warren and pretending to be native. It’s also totally incoherent to claim they’re a separate country but were also justified in looting billions of dollars worth of gold from “its” land, as if Beijing isn’t a thousand miles away from Taipei.
As for the civil war being easy, the KMT had the support of every US president, Stalin, and Hitler, which is just to say they had everyone’s support. The KMT flag would be over China right now if they had simply not tried to murder the communists in cold blood. I guess they did make things hard on themselves.
