Answer:
pretty sure its because Clemenceau had wanted Germany weakened to the point where it would never be a danger to France ever again. He was angry that France got the Saar coalfields for only 15 years, and he was angry that the Rhineland was merely demilitarized – France had wanted it made into a powerless independent country, and Germany split up. Also, reparations were not high enough for Clemenceau. He wanted reparations so high that Germany would be crippled and paying for ever – when the Germans defaulted in 1923, France invaded and took them in kind.
