Actually I agree with oak. They got nothing maybe not even the hydrogen bomb. They will have planes testing the air to see exactly what they did do. I think we should wait to those results come in first. Korea knows they really attack someone North Korea ceases to exist. Then we have to act. Mean while china does 2.5 billion a year with North Korea. China does over 600 billion a year with the US. That is a lot of Tucan can openers if they do business with Korea they might not be able to do business with the USA. I think china thinks we are more important to their economy then Korea.
