Raider old boy, I know nothing of modern diplomacy, but certainly Confucius and Lao Tzu and Sun Tzu offer some insights. but don't ask me even what "within our means" suggests..... you alluded to it and I said it straight - we are indefensible should China decide that they should assail our largest island home......
crikey they could land anywhere along most of the northwest and we'd just think they were FIFO workers at the coal mine.
for thousands of years the Chinese have had many wars and overthrows and colonialist expansions and contractions. The Emperor images of Gilbert & Sullivan obviously don't do justice but the Chinese movies certainly do.
you ask for 90-ish% functional capability...... what do you have in mind?
