Not really. The world got other problems. Europe is out for now, since we got Fascists at our doorstep trying to conquer Ukraine. The US has the orange clown as president, who is cozy with Putin. I don't think you can ascribe it to others being cowards, if "the world" doesn't react to protect Taiwan. It is right at China's doorstep. The logistic imbalance of trying to protect Taiwan, being this close to China is insane.
In the end, if a war happens, it will be idiotic again, from an economical point of view and from a humanitarian point of view. Economically, of course it will cost huge amount of resources to conquer Taiwan, and it will only disturb trade and what is already established on Taiwan. From a humanitarian point of view, of course many people will die.
The smartest China could do, would be to return to a soft power approach, and continue to develop mainland China, to continue to rival and even surpass Taiwan/Taipei. There are many young people, who don't have the walls in their minds, that the older population has. They don't want war, they want their freedom, and they want a high living standard. All this would be theoretically possible, if China didn't let ideology rule, but instead went for the economically best route, which is most certainly not an invasion.
China's takeover of Hong Kong proved that any notion of "one country, two systems" is a total lie and assurances from the Chinese Communist Party are completely worthless. There's no coming back from that, at least as long as Xi Jinping remains in power. Young people in Taiwan are less supportive of reintegration with the mainland than ever before. Fewer of them even have direct family ties there now.
