Imagine what would happen if Roosevelt would target only leaders...

Among 66 million Germans in 1945

17M were mobilized for Wehrmacht Service

8.5M were members of the National Socialist German Workers' Party and definitely many of them did not supported Nazi ideology and joined the party for career reason

1M served in SS

30,000 served in Gestapo

Imagine, how World War II would end if Roosevelt would target not Germans (the majority of them were innocent), not the members of Nazi party and not SS officers, but only the leaders of Gestapo …
