North Korea is moving forward with its development of an ICBM that can carry a nuclear warhead. Will Pyongyang test it, challenging Washington to strike its nuclear reactor in Yongbyon? If Washington does strike, will Pyongyang choose to react passively as Syria did in 2007, or will it respond by starting a war with South Korean and American forces in the region? Although both sides use militant rhetoric, neither will choose to challenge the other. They will instead upgrade their deterrence capabilities.
