When all of the world seems to be pressurizing you to choose between two unwelcome outcomes, it takes great intelligence to think outside the box.
Most take as their only options those presented as such by authority figures and other powerful people. Mostly there are no choices apparent in the process, particularly when a nation is at war.
You do as your government directs, even if that way seems deadly, demanding sacrifice as standard. All history, tradition and peer pressure colludes against your right to survive. Media, clerics and other sources of information encourage your assent; justifications shifting according to epoch and location.
It requires tremendous wit to see past such an onslaught and discern further choices beyond the given. Then great courage and self-possession to follow through, selecting one of them instead.
