North Korea is threatening nuclear war again

The north korean army is no joke - that's what makes them a credible threat to their neighbors and a thorn in the worlds side - they have almost 3 times the special forces that we do and very advanced weaponry. There is no way the US could just walk in there and squash them - we might win eventually, but it would be a very long, very costly and very bloody venture - not to mention the fact that their biggest buisness partner China would almost definitely wade into the conflict - which would instantly turn the tide heavily against us.
