But the tit-for-tat is totally relevant! At least for things happening in the present day. Most people's countries are doing things you disagree with: but within a country, even if you oppose someone doing something, you can usually sympathize with the rationale behind it. When the media deflects attention to those evil people with different color skin across the ocean, it's very easy to simplify things.

Case in point: those escaped North Koreans weren't merely refugees but defecting soldiers who had shot their superior officer. Do you think China liked being in that situation? You can either cause a major international row with a nuclear-equipped rabid dog who for historical reasons is sitting a couple hundred miles away from your capital, or you can send a rebellious military unit back for certain execution.

What would you have done? And let's make this sharper: what would your country's military bureaucracy have done?

Why not let people who have actual local knowledge and care about changing things focus on what local people's actual priorities are and the real pain points for human wellbeing?
