North Korea:)
Communist Russia, North Korea, Vietnam, And any other Communist Country. Communism is a military controled Government.
North Korea was not in WWI
Politically, North Korea is a strong power. Militarily, North Korea, a nuclear power, with a 9.7 Million Reserve, and 1.9 Million active personnel is among the top military powers in the world. However, Economically in the early 1980's its neighbor South Korea surpassed it economically and natural disasters, mismanagement, and the collapse of the Socialist Market in the 90's led to a economic collapse which makes it weak economically.
I believe the Soviets were occupying North Korea because of the Communism.
North Korea:)
your question does not make sense?
The US is not permitted to patrol North Korea, nor do they. The US military does however have military bases in south Korea as part of a treaty to protect them against a possible attack by North Korea.
Military jobs or farming. North Korea believe that to be a strong and powerful country you need to have a powerful and strong military.
500,000 people serve in north korea's military
North Korea is a communist nation that wants USA out of the peninsula, so they build up on the military. Also, South Korea depends on the USA for funding their military.
United States
Mostly in military and mining
Absolutley there barely is even an economy North Korea mostly focus all their money to the military
the United Nations forces, which protected South Korea from an invasion by North Korea.
No South Korea didn't envade North Korea. South and North splid up because of the alliance between North America and Russia was not good. North Korea is the one who attacks first all the time. We never started first. North Korea's ruler does not feed his citizens he uses the money for nuclear explosions.
Not an expert but overtly I do not think the US has a military presence in N. Korea. Covertly I am sure that there will be one or two spies there.
