weapons alone do not make one to a military power.
cambodian army is no match to vietnam. I don´t remember how many times we beat them with ease, colonized their country and civilzed their people. even if you successfully instigate all armies of laos, cambodia, thailand and burma combined to go to war against vietnam, their armies had little chance against us vietnam, and would be annihilated.
that is not a joke. we have shown that in the past, when our army defeated the Ming chinese army in the northern, champa army in the southern front, crushed all regional armies combined from laos to cambodia to thailand to burma.
but that is not enough, back then, just when we intended to invade malaysia, the Ming threatened with a total war against vietnam, plus the muslims on the penisular threatened us with jihad, we stopped.
have you forgotten we annihilated the armies of Mongolians and Manchu, while they conquered China, took your women and made all males to slaves?
So feel free and laugh at vietnam.
