The news over the weekend that a few South Koreans have become fighters for Ukraine against Russia generated quite a chatter. Former navy lieutenant and Influencer Rhee Keun, also known as Ken Rhee, has been posting pictures since four days ago hinting that he and "his team" were bound for Ukraine and are in fact now on the ground.

Rhee Keun's Instagram post Tuesday from Ukraine says, "The world helped Korea during the Korean War. [...] Now we will help Ukraine."

There has been much good will toward Ukraine in Western countries, and South Korea, too, has shown outrage at the Russian invasion. But some of its people are asking whether it's good for the nation that citizens like Rhee are heading to war.
