Failure to do this will mean that the Americans have effectively ceded the South China Sea, parts of the East China Sea, the Taiwan Strait, and even the Yellow Sea to the People’s Republic of China.
Once that happens, the Chinese then move with great speed to push their power beyond that First Island Chain all the way to the Third Island Chain (which includes Hawaii), and it’s a whole new ballgame.
It's interesting how they never properly analyse how a war with China would play out outside of Chinese waters. It's almost as if China (or any other country, really) would never bother waging war against the USA outside its own territory.
Although I agree and admire the enthusiasm, you should really add "get organised" to your list. Revolution without class organisation is anarchism, and you don't actually need to be great at every single one of those things you listed in order to be prepared.
However every single party should prepare for the scenario of illegality and military conflict you seem to be prepping for.
