In a just cause the weak o’ercome the strong.

A cause that is genuinely fair gives people something power cannot buy. It keeps allies from drifting off, it lets you absorb a setback without losing your nerve, and it makes the other side spend energy on justification. Strength wins most contests, but it has to keep explaining itself when it is plainly in the wrong.

This is worth testing before you rely on it. Describe your position the way your opponent would describe it and see whether it still looks fair. If it does, you can afford patience; if it does not, the weakness sits in the cause rather than in your effort.
