Would the US wage a war that might kill millions of South Koreans or Japanese without consulting South Korea or Japan? It would be a colossal mistake, but the US government has made a lot of colossal foreign policy mistakes lately. From Robert Perry at strategic-culture.org:
If Washington takes action without consulting its allies, the alliances themselves could fray
Tough North Korea rhetoric from the U.S. administration continues. Major South Korean media increasingly talk as if U.S. air strikes are likely, and theexpert community seems increasingly resigned to them as well. Despite constant criticism of his incendiary language, President Donald Trump continues to suggest that major action against North Korea is imminent—most recently by suggesting that we are now in a period of ‘calm before the storm.’
I have argued in these pages that such strikes would be an enormous risk. We do not know what the North’s redlines for retaliation against such a strike are. We do not know if the strikes would so unnerve the North’s elites that war was next, that they would respond with enormous force, possibly including nuclear weapons. An expert study of this scenario suggests appalling casualty numbers. We also do not know what China’s thresholds are for intervention. China is treaty-bound to help North Korea if it is attacked. It may not, but if a U.S. air strike against North Korea spirals into a major conflict, then the likelihood of Chinese intervention rises.
White House officials, most importantly Secretary of Defense James Mattis, continue to suggest that diplomacy is the preferred outcome. And there are options to continue to buy us time against the North Korean nuclear and missile programs: missile defense, sanctions, continuing to cajole China to push North Korea harder and so on. Nevertheless, the pressure to something dramatic regarding North Korea is rising. If war is inevitable — it is not, but for the sake of the argument—it is better to fight now, before they have more weapons, and before those weapons can more evidently strike the continental United States. Even Kim Young-sam, South Korea’s president at the time of the 1994 nuclear crisis, has retrospectively regretted his decision not to strike then.
