Who's threatening whom?

The US routinely threatens North Korea, sending planes and ships near their coast and above their skies. Every year 75,000 US and South Korean troops conduct two weeks of war games known as Ulchi-Freedom Guardian exercises which usually provoke a North Korean response. Last year the response was their fifth nuclear test. Those 10 nukes are the best war insurance policy North Korea could possess. The US is not interested in a peace treaty between the two Koreas. Nor is it interested in normalizing relations with North Korea. Its first three priorities with North Korea are regime change, regime change, regime change. Iraq gave up its nuclear weapons program and got its regime changed. Libya gave up its nuclear weapons program and got its regime changed. Both were accomplished not from within, but courtesy of Uncle Sam. Kim Jong Un may be crazy....but he's not stupid.
