The no-win scenario
Those who are fans of Star Trek will be aware of the significance of the Kobayashi Maru. It was, in the original timeline, a test given to a cadets which was designed to be an impossible, no-win scenario. The test showed how they would react when all hope was lost and the crew faced imminent death. How would they cope knowing they had they no way out? Politicians almost always leave themselves wiggle room, a way to pivot out of a previous position.
