Why did the Big Three after WWI disagree so strongly?

After four long and difficult years for all involved, World War 1 was officially declared over in October 1918. The tide had turned against the Axis, and Germany had lost the war. The devastation caused by World War 1 was enormous, with France bearing the brunt of it. All told, 17 million civilians and soldiers died, with 300,000 homes, 6,000 factories and 1,000 miles of railroad destroyed. Much of the damage was in France, and the cost of the devastation was inconceivable. …

…hand, England, a country that was not devastated by Germany, and was not too removed from the situation, was clearheaded enough to survey the situation from an appropriate distance without letting emotions or apathy rule their decisions. The Big Three had one thing in common--they led the Versailles conference and were the prime movers in any decisions made. The different experiences that the three leaders had with Germany were the main factor in their disagreements.
