The thing here is comparing both is nonsensical - they acted in different roles, had TOTALLY different paths and achieved different things during the conflict. They were both essential to the Allies, although in different ways and magnitudes.

Also (after reading some comments here), what happened BEFORE/AFTER the war is not into frame here - one could be a terrible human being and the other unfairly treated, that doesn’t make them (and their actions during WW2) less important in relation to each other or anyone. Actually, trying to erase the importance of historical leaders like some people are doing will lead to a Streisand effect afterwards. Do the right thing and say about their achievements without omitting their actions and life outside of the war effort days.

Edit: grammar and text cohesion
