War is not a joke, it does no good to both sides.

The Chinese leadership is well aware of this and is massively funding efforts to build these indigenously, but they're chasing moving targets and still decades away from catching up.

you watched too much MSM

1. the whole taiwan thing is just an excuse to force the united state to waste more resources on a topic selected and controlled by China. nothing is better at wasting US efforts by forcing it to keep investing borrowed $ in its military presence over 10,000km away from its mainland, nothing is affordable at such distance.

2. Taiwan doesn't make those ASML machines, they operate those imported machines very efficiently, that is all. China is playing a long game, trying to master and eventually control the full semiconductor supply chain at any cost by developing its own industrial bases. In such a big picture, Taiwan with what it has today is tiny, it doesn't worth such an invasion. With 1.4 billion population and its ongoing competitions with the US, China doesn't have the luxury to select which sectors or fields it must control - it has to control everything to just have its people employed on half decent pays.
