There is a tiny little problem, Taiwan is so close to China that is basically indefensible, is it at range to even the shortests range Chinese ammunitions. China can also makes life difficult to US in other areas, like for example, Israel, which is more important for US than Taiwan or the Baltics in Europe, China and Russia could help Iran to get nuclear weapons faster, making sure that Israel existence is threatened or Russia take over the Baltics. In order to maintain its primacy the US has to project power all over the world, China has only to project all of their power in a island that is on its front door and once they started they are not going to stop.The issue is that it seems the US has control of the time and place the conflict would happen. Eg. They have more control over Taiwan's political system and thus influence when Taiwan will declare independence. They have more informed over chinas external security environment than the other way around.
That needs to change. China needs to prepare even more so than the US so that when the US is prepared, china would have been prepared much longer.
If the US accuses china of weaponizing space, china should immediately throw the accusation at the US and start weaponizing space right away. Otherwise China will always be just responding and not taking the initiative.
I hope China is doing these things already and are just keeping it under wraps. But China cannot let the US dictate when and where the conflict occurs.
