* The peace treaties were negotiated between multiple countries, each with its own interests. The victorious countries had to compromise to reach a settlement that all could accept.
* The victorious countries had different war goals. Some wanted to punish Germany for starting the war, while others were more interested in gaining territory or economic concessions.
* The victorious countries faced domestic political pressures. They had to consider the interests of their own citizens and the need to maintain public support for the peace settlements.
* The victorious countries were concerned about the future. They wanted to prevent Germany or any other country from starting a new war. They believed that the peace settlements they imposed would help achieve this goal.
As a result of these factors, the victorious countries did not receive all they wanted in the peace treaties. However, the treaties did achieve their main goals of punishing Germany and preventing a new war.
