c)europe’s desire to maintain original pre-war borders  

d) the allies’ desire to seek retribution for germany’s actions

the correct answer is d) the allies’ desire to seek retribution for germany’s actions.

the allies’ desire to seek retribution for germany’s actions had the greatest influence on how germany was treated after world war i.

it is estimated that the cost of wwi was around 260 billion dollars, and the allies wanted germany to pay a big part for the losses. the allies also wanted to impose land losses as well as limit the army of germany and confiscate their industrial resources to apply the retribution.

in the united states, president woodrow wilson created the fourteen points to be delivered to germany, as a peace program. he presented these documents to the u.s. congress in january 1918.
