The British and the French leadership didn't want the 14 points because they believed that the fourteen points did not punish Germany as severely as it deserved for its participation in the war and the war crimes that they committed.

This is one of the reasons why Germany had a huge crisis in the upcoming period and why they started supporting the rise of Nazism as an answer to this.
