we had a nuclear umbrella. the USSR was our military ally back then. when the war broke out in 1979, the russians deployed 600,000 men army to the USSR-china border. AND mobilized about 400 short and medium tactical nuclear missiles. china could be turned into nuclear ashes if they were the first that resorted to nuclear strikes.
yes, I believe we need similar umbrella today, if we feel the Chinese begin to run amok.
no, sub-Mekong delta empire is niceguy´s dream
bro, you should place more trust on Vietnam.
