Sanctions

Sanctions, like boycotts and blockades, only work when the government or ruling party (military of individual) cares about their people.
In the case of North Korea – and it’s not that I want to judge Kim Jong Il but – I would suggest the leadership doesn’t care. Millions of people starving to death over the past decades are only the beginning of evidence of this.
So as every nation decides to side with South Korea and up their sanctions the only people that are going to suffer are the average person. The rich will have ways around it and the leaders don’t care.
With more than $200 million not showing up in the country, that's a lot of people to suffer.
The problem is I can’t come up with a better way to tell North Korea that it can’t blow up South Korean ships.
