ha ha ha...you are clueless and a liar.
I guess you probably don´t know when Vietnamese army implemented guerrilla tactic against the foreign forces for the first time? do you seriously think weapons decide a war?
the armies of Thai, Laos, Cambodia and Burma combined have more personnel, money and weapons than Vietnam. do you think their armies combined have a chance against Vietnam? No, of course not, as history shows: in the 15 century, Vietnam army reached as far as the heartland of Burma kingdom: the irrawaddy river.
you provided the Cambodians, the red khmer weapons, trainings and military advisers. but Vietnam crushed their entire army in just a week.
