I don't understand how they think arming Taiwan will make China less aggressive about this? How would the US react if China had a military base in Cuba like the US has in Taiwan? Of course China is being aggressive about this, it's a threat
Also Taiwan doesn't exactly see itself as distinct form the mainland in the way the article implies. Taiwan insists that it is the real china and the mainland is their territory while the mainland believes it is the real china and Taiwan is it's territory. It's a strange situation.
China's being aggressive because Xi is throwing a tantrum over not getting what he wants. It's nothing new, nor is it anything we haven't heard before from him. I don't know why this is considered news.
Confidently said by someone who doesn't understand the Chinese governmental system. It isn't a dictatorship, not everything Xi says goes. Major decisions are discussed thoroughly by a large board before any action is taken. If Xi was making shitty childish decisions that the party saw as short sighted and foolish the party would act against him. He isn't all powerful.
