I agree with this, but it also depends on the time frame when this occurs. By next summer, the US should be completely out of Iraq, leaving Afghanistan as the only distraction to Korea. While that's a major distraction, I would expect that Afghanistan would take a back seat to Korea in the even of a hot war in Korea, thus we'd have 1 full war in Korea and one half war in Afghanistan. In addition, the only way war will ever occur in Korea is if NK attacks first. In such a scenario, SK will not have difficulty finding allies. I would expect a similar scenario to the Korean War, where many other nations deployed sizable contingents to aid SK. I would expect to see significant deployments by the UK, Australia, Canada, Germany, and France, and many smaller contingents from other western-aligned nations. This would be a much stronger international alliance than we saw in Gulf War II; more on par with Gulf War I. That said, those deployments would take a while to arrive.
