It's quite different.
USSR want to nuke China as direct conflict .. same to USA nuke to Japan ...
Whileas USA want to nuke China to protect Taiwan, nuke North Vietnam to protect South Vietnam, nuke North Korea to protect South Korea ...
Now, from above conflict, only Vietnam reunited ... and the relationship between unified Vietnam and USA is good.
We just want to make sure, when USA, Russia want to use nuke to China to protect Vietnam.
About the position, Vietnam feel strong enough to stay independently, deny ally to someone against others ...
They wanted to nuke NV because they hate it
