[My answer]
Taiwan was in a very dangerous position during the Cold War. At that time, the two largest forces in the world were the United States representing capitalism and the Soviet Union representing socialism, and the Soviet Union was extremely partial to China. If the Soviet Union became the world leader, it would pose a great threat to Taiwan, so it made a precarious position for Taiwan .
As for the problems left over from Taiwan after the end of the Cold War, I think they are more spiritual, but in fact I don't think these problem can be regarded as a completely negative impact. That is, the decline of Taiwanese people's national awareness.
When our grandparents were young, they might talk about counterattacking the mainland and want to regain the territory that was once Taiwan, but after the Cold War, Taiwan's ideology has changed. The young people of today's generation have a greater sense of belonging to Taiwan than to China, so they don't talk too much about counterattacking the mainland. I think part of the reason for this shift is the Cold War.
