Clearly North Korea is a very strange situation because it is such an isolated country run by a handful of dictators, or maybe just one, who seems to be somewhat paranoid. And, who had nuclear weapons.

The middle class is collapsing and we are moving toward an oligarchic form of society, where the billionaires will control the economy and the political life of the country.

One of the ongoing crises in America is institutional racism. We have a very broken criminal justice system. We live in a country where there are more people in jail than any other country on Earth.
