I'm sure you can think of a personally meaningful example if you try; have you turned on the news lately? There's a big story that people seem to be having a hard time finding a win/win and people are starving and being killed.

Sadly, that description doesn't even narrow it down to one "no-win" situation I can think of, so your comment is slightly concerning on its face.

I asked as a chance (a challenge even) to reframe an arbitrary situation.

Even the one you mention, at this exact moment, a win/win could be framed around the benefits of stopping the war. While it's entirely reasonable to pick a perspective that focuses on the awfulness that has occurred, looking ahead, a peace deal would benefit all sides. Certainly it's closer to win/win than continuing down the current path.

My point is that the perspective we take is a choice.
