North Korea published a "long sentence" on the 21st in the labor newspaper titled "Our Progress is Stolen and Strong". "Expression" is an authoritative text that North Korea uses to communicate its intentions and policies to its people.

North Korea admitted in this article that it suffered tremendous suffering from sanctions on North Korea.

"Even after the post-war ashes and the march of suffering, we have been able to say that the difficulties we faced in the 10th century of the present century are in fact the toughest trials in the history of the republic."

The difficulties North Korea faced in the 10th century, or 2010, of the present century were the most severe trials in North Korean history. However, North Korea emphasized this trial and pulled out the timing of postwar reconstruction and the period of hardship for comparison. More specifically, it seems to refer to the period of recovery after the Korean War in the 1950s and the "march of suffering" in which millions died of starvation in the mid-1990s.
● The "march of hardship"

I will take a brief look at the 'march of suffering' that appears in North Korean history to help understand. North Korea says there have been three "marches of hardship" so far. The first is the period from December 1938 to January 1939, when the anti-Japanese guerrilla forces led by Kim Il Sung sacked and pursued the pursuit of the Japanese army. During this period, the Kim Il Sung unit had to march in battle with the Japanese army as it suffered from the coldness,

The second slogan of the "march of hardship" in North Korea came after the Korean War in the 1950s. North Korea called the "hardship march" a difficult time for recovery in a situation where almost everything was destroyed by war. The third word 'march of hardship' came from the death of Kim Il Sung in 1994 to the end of 1997. It was the time of the collapse of the eastern socialist country, the isolation from the outside world, the severe economic downturn and the subsequent floods of millions of hungry deaths.

● The core point of the labor newspaper is

When we go back to the articles of the labor newspaper, all the examples that North Korea pulled out to emphasize recent trials are the "marches of hardship" of the past. Two other cases, apart from Kim Il-sung's anti-Japanese armed struggle, have contrasted the two "hardship marches" since the North Korean regime with the difficulties of recent sanctions.

I think it is this pressure on the sanctions that North Korea feels, but it is not the core of the labor newspaper. North Korea claimed in the labor newspaper,

"It is a national pride that it can not be left to starve, freeze and die."
"Self-sufficiency is hard and difficult, but it is like a pillow that strengthens the nation's power." (Foreign tax) Dependency is easy and temporary, but it is like a remedy that makes the people helpless and declines their national power.

North Korea's negotiations with the United States have made it harder for the sanctions to be lifted, but stressed the willingness of the United States to resist pressure even if they die of starvation. It is the context of self - regeneration that has been emphasized recently.
● "I will starve to death"

It is still unclear what the North Korean leadership has done since the breakup of Hanoi. This article from the Labor newspaper may have come from the intention that it is necessary to catch up with the people's ideals once the prospect of North Korea negotiations is unclear.

However, the fact that North Korea is thinking about returning to the past makes it worry that the emphasis should be on maintaining its self-sufficiency even if it starves to death in a more difficult time than the "march of hardship". The direction North Korea should pursue now is not to protect itself but to find ways to prevent the people from starvation.
