Humans tend to solve a problem, forget they solved it and resolve it again or constitute other headaches and have to reapply their solutions. This is cos they assess their feelings and make decisions based on it. When a problem is resolved, the feeling about it changes to a positive vibe. Unfortunately, future generations who were not party to the resolution may not feel the same way as others who resolved the problems felt. This is why treaties are bent, cast aside or sometimes outrightly destroyed.

There has been no generation that didn't know the advantages of peace in the end.
