Vietnam nah go a war
With no more kung fu nun chuckle
He mentions Vietnam as an example of more advanced warfare. Gone are the days when wars are fought with bare knuckles and simple tools where you actually have to stand within a meter of your opponent. Wars are now fought like cowards.
“Nun chuckle” it is a play on words to fit the rhyme, he means a nunchuck (as it is usually part of multiple martial arts including Kung Fu)
