It's actually Chinese scientists who are making hydrogen bombs in North Korea. North Korea is not capable of developing such powerful bombs. China will backstab USA in case war breaks out in between US and North Korea. If North Korea was able to make such bombs then Shri Lanka, Nepal, Philippines, Malaysia, Vietnam, Pakistan, everybody will be doing it. Even though sanctions have been passed against North Korea, China would continue to provide for North Korea through smuggling across the border. China wants to destroy America in fact, not North Korea. Kim John un is nothing but a dumb  alcoholic. China is the mastermind of all this
