subsequent turmoil and instability in Russia didnt last too long, Putin, a member of communist party, took the power and keep Russia in stability and safe till now.True. We agree on something at least. It's true that no dynasty , ruling regime or party can rule forever. In fact the CCP and VCP have done well ruling alone for over half a century actually . Not sure how many decades they will last. However , the issue here is that being a one party state where no other party is allowed to hold power or rule, this makes the country potentially volatile in the long run, since in case there's a political turmoil or nationwide uprising/protests that leads to the toppling or collapse of the party then there's a high chance of the country facing a turmoil as the state itself collapses. This is the case due to the fact that one party state or one man rule(dictators) often focus everything on themselves alone . The party or the person is above the state itself. In short, you can not hate the party and love the country. Since the party itself equates itself with the country. In fact the party even puts itself above the country. So you hating the party is the same as hating the country ( that's what the official line will claim anyway). So since the party has already equated itself with the state/country and made sure every institution, company, public organisations, educational institutions etc is part of the party or follows the party line , any collapse or fall of the party will lead to major instability/conflict as different players justle for power to fill the huge vaccum. That's the main issue with such system. We saw this when the Russian one party communist party collapse during the end of the Soviet union and the subsequent turmoil and instability the country went through/witnessed.
So hopefully as Vietnam develops to a certain extent/level the country will reform politically and open up democratically like S.Korea, Taiwan(KMT ) etc did when they developed and grew wealthy.
NB: when a man grows rich and wealthy , the next thing they usually desire/value more is liberty/freedom to criticize and express their views without any fear of repercussions/repression.
Btw, VN is quite different cos VN is quite small. VCP also know clearly that VN will not survive under US sanction if we cant unify sub Mekong region to become stronger . Thats why VN invaded Camb in 1979, attack Thai from 1979 to 1988 and only withdrawed when VN tank comander totally control Camb miilitary forces.
If we cant unify sub Mekong region,then VN will be split into half again. Thats why if CCP keep stopping VCP unifying sub Mekong region, then even VCP leaders like Le Duan will also wish for CN collapse again.
