Ah, but like many sound ideas, they're not workable when put in to practice because the old conflicts re-surface and are never forgotten. The French have never forgiven or forgotten Trafalgar and Waterloo.

This was admirably demonstrated by the actions of De Gaulle after WW 2. He never forgave us for eventually "saving" France......... Look how he behaved over those from the allies who worked under cover with the French resistance?

Also, time moves on, what may have been good intentions of sixty years ago can easily turn in to a nightmare when influenced by later events. Remember that most of the evil in the World is done by people with good intentions and also that the road to Hell is paved with good intentions.
