I've always thought that the real threat to the US in a war with China, would come from the sleepers in the Chinese communities that are in every city in the US.
You are very wrong on that count, good Sir. Historically, especially during the first world war, there was a lot of suspicion about the German origin soldiers in the US Army as the fight was against Germans in Europe. But, their American-ness won the day, and they fought with more gusto than the rest of the lot.
Recently, there was the "Islamist/ pan-Islamic" scare, but the Muslims of America proved resistant to that call, even as Europe crumbled.
Therefore, it is almost inevitable that the American Chinese with origins in Mainland China would fulfil their duty, and more, for the US Army when called upon to fight the Chinese Communist People's Liberation Army (PLA).
In fact, I'd recommend that the next time a US Naval warship undertakes a "freedom of navigation" voyage in the South China Sea, they take along some Mainland China origin Chinese Americans (whether regular sailors or temporary conscripts). Then, at the height of imminent confrontation, let these Chinese origin sailors man the decks, and blare out loud from loud-hailers in their fluent Mainland Mandarin diction. The thought that now it is Chinese settled in America fighting against the Communist PLA Navy would be extremely disquieting to the Communists and rattle the nerves of the PLA Navy. The PLA Generals sitting in their Peking offices will no doubt draw the appropriate comparison with how the German origin American soldiers destroyed the German Wehrmacht in both World Wars.
Army can spend all budget money without any problems, just think what is the cost of modern warship.
