There isn't a war today. However China wants Taiwan: war is future option they preparing for - they might or might not go to war but they are clearly preparing. The US is likely to get involved in such a war and I would expect Europe to join in as well.
Don't ask me what Trump is doing though.
Don’t take China on face value, they have every incentive to promote a grifting military industrial complex in the US while focusing on competing in manufacturing. An actual war would fix a lot of the grifting in the US as it would align interests. Pretending they’ll go to war over Taiwan and not doing it is an effective strategy for undermining the US.
China going for Taiwan would be the worst geopolitical move of the century, potentially worse than Germany's decision to invade the soviet union. They talk about reunification because it's good propaganda and both sides want it to a degree, but doing it forcefully just isn't something China would realistically do unless they really don't like their path of becoming an international trade and manufacturing hub
