People (most people) eventually wise up to their mistakes, try to correct them if possible and vow not to repeat them.

EG: "We are not going to close our eyes what a dictator does again"

Some of them think that no action is the best action because they can't screw that up. They think that if other people are making futile attempts and that exonerates them if the attempts do not solve the problem.

EG: "The UN is working on it for the 12th year and we should not interfere. That way the blame will be on the UN and I won't have to feel guilty."
