North Korea's $30 billion economy is tiny but big enough to have nuclear weapons, and 1 million soldiers in offensive formations aimed at Seoul. With most of its few resources dedicated to arms and a Communist elite, the economy does not produce enough to feed or shelter its people. Starvation in North Korea is as real as the nuclear weapons and would be worse without international food aid.
The North Korean $30 billion economy is 0.2% or 1/500th of the American economy's $14.5 trillion 2010 GDP. North Korea's economy is 3% of South Korea's annual GDP of $1 trillion.
No economy or people in the world are less free than North Korea and the results are horrendous and dangerous.
