A ROK Drop favorite Andrei Lankov explains why Russia is going to attempt to water down United Nations sanctions on North Korea or veto them all together and it has nothing to do with Putin taking an anti-US position:
Vladimir Putin was right when he recently said that even if North Koreans have to eat grass, they will not surrender nuclear weapons (of course, in North Korea the people who make decisions on nuclear weapons are far removed from the people who would have no choice but to eat grass).
However, there is the probability that a really harsh sanctions regime will eventually provoke a grave political crisis and revolution in North Korea: instead of eating grass, the people will rebel.
For American observers, who will watch enthusiastic TV reports about a North Korean revolution in safety, this development, as long as it does not trigger a region-wide war, will be welcome. After all, regime collapse will bring about the complete solution of the North Korean nuclear issue, the U.S.’s overwhelming concern.
However, Russia and China, inconveniently located on the border with North Korea, have reasons to be unenthusiastic about prospects of a Syria-like or Libya-like situation, anarchy and civil war in a nuclear-armed country nearby. For Moscow – and, for that matter, for Beijing – a collapsing North Korea is a greater threat than a nuclear one, however bad a nuclear North Korea is. [NK News]
