Are you factoring in the most rigorous sanctions

China is a major ally to North Korea, and obviously Russia is too. Why wouldn't it be enough trade to have access to the biggest global market in the world (China), and the market with the most natural resources too (Russia).
North Korea has plenty access to trade, this is not like Cuba or even Iran. North Korea has constantly threatened surrounding countries including Japan. Cuba hasn't and even Iran didn't threaten their neighbors more than than they were threatened by their neighbors. Iran actually made an agreement with USA and EU. North Korea never wanted to even negotiate, except for easing the famine caused by extreme North Korean incompetence.

Do you understand how crazy you sound? not to mention your premise is entirely false

When you are starving in the province, it doesn't help that prestige apartments are built in the city. We have seen other dictators do this too, and it does NOT improve living conditions, on the contrary it is spending resources in a way that doesn't benefit either the people or the country. If you can't afford food, chances are you can't afford to rent an apartment in the city either.

Do you know how many people outside of the western periphary capitalist countries are malnourished? much much more

No other country has had so consistently repeated famines as North Korea, just look at South Korea, and you can see how a better managed country with almost the exact same geographic conditions and trade opportunities can work. If you can't see the difference in how badly North Korea is managed compared to every other country in the world, then you are blind to reality.

Did epstien told you that?

Are you insane or a child? How is Epstein in any way relevant to this?

which america invaded the DPRK killing its 12-15% population

First of all, the peace agreement was entered in 1953 after 3 years of war. Not so long after the communists took over in China in 1949. China has moved on and recovered after the WW2 occupation by Japan and the civil war after. North Korea has had 73 years to recover, but is arguably worse today than they were 73 years ago.
To continue to blame "the west" three quarters of a century after is insane, and a willful act of denying reality.

There is absolutely nothing good about North Korea, and the North Korean regime has no excuses for how bad it is.
The people however, are probably mostly innocent victims to circumstances that are very hard for them to change.
Why don't you consider the plight of the malnourished and oppressed people of North Korea? Instead of defending a regime that is among the very worst and most cruel and brutal in the world?
