"Injustice anywhere is a threat to justice everywhere."
Like someone else also posted, it is not a communist regime, far from it. It is a fascist regime - just like in North Korea, USSR and some other countries. And even in the US - however in the US, the fact is (or was) hidden from the people for a long time. When people rebel, at last you see what a country really is. We don't have to look at North Korea to see "OMG DICTATORSHIP".
Simply look at who owns the place.
Is it the people? Good. (Iceland)
Is it a handful of people? Not good. (USA, North Korea, Vietnam)
Power corrupts. That's what it boils down to. It's my hope that Vietnam can get the revolution it needs. Granted, I know nothing about how the whole situation went down.
I read somewhere that people who are less ignorant, more knowledgeable about what goes on, tend to be the most depressed. Ignorance is bliss, as they say. In theory, it would serve a country well if all it took were ignorance to keep the populace happy, however the ignorant are the most dangerous, most likely to violently lash out. It would pay off in the long run for countries to educate the masses and change their ways where possible. Or be honest if they can't live up to their promises.
This is just my idealized view. I know it's a lot more complicated than that. Few people actually want to be saddled with such knowledge, because it would force them to be more responsible. XD; I'm sorry. I'm rambling...
