On New Year's Day 1942 the Allies declared they were fighting "to defend life, liberty, independence and religious freedom, and to preserve human rights and justice"
It's a bit tongue in cheek, but maybe avoid the red witch hunts, avoid murdering your own population for being black or revolutionary (or both). And for the French and British, not executing colonial soldiers and their families to avoid paying them (or to avoid respecting your promises of Freedom(tm) )
Maybe it was just a troll, but implementation is clearly not finished yet, and was surely not at the end of the war.
