PDR of Korea - Is the cold war really over?

Did the cold war really end? Of course we have that last remnant of the Soviet empire, Cuba, but there is also the Democratic People’s Republic of Korea. And if we are to believe that the cold war non-sense is gone from that conflict, we only need to look at a recent article for National Geographic; “Escape from North Korea.”
It comes complete with old cold war rhetoric such as “escaping communism” and making it to “freedom.” One comment in the National Geographic article states: “In the border city of Yanji a missionary cautiously looks for North Koreans needing help on their long journey to freedom.”
Of course the north is not a true worker’s paradise but neither is the south. The so-called “freedom” found in the south is rather limited. Wages are stuck low, competition for jobs and living space are fierce. And much of the lights and “glamour” of the south’s capitol is more like capitalist clutter than some kind of milk and honey. There’s also a lot of pollution in the south.
Yahoo News also states that recent missile launches by the sovereign state of DPR (North) Korea are being met with threats from the US:
“At the United Nations, Japan's U.N. ambassador, Yukio Takasu, said his country would request an emergency meeting of the Security Council to discuss a possible response if North Korea launched the long-range missile in the coming days.
The United States and others have threatened North Korea with punishment if they launch the long-range missile.
"They're doing everything consistent with the launch of a space vehicle on April 4," the U.S. defense official told Reuters on condition of anonymity.”
Considering the fierce independence of the DPRK, it is unlikely that threats will ever bring any positive change to that country.
