Positive change comes when individuals, groups or countries open to possibility and let go of blind resistance and of resentment of “the other”. As Joe said “the opposition” is not the enemy. I would add from years of facilitating change and resolving conflict, two other aspects: Assume positive intent and drop the self-righteous anger. If you find yourself preferring to be right than preferring to have conditions improve, then guess what? You are perpetuating the problem.
