• The Second World War rages on Earth. (TOS: "The City on the Edge of Forever"; VOY: "The Killing Game", "The Killing Game, Part II"; ENT: "Storm Front", "Storm Front, Part II"; et al.)

• In an alternate timeline, Edith Keeler is saved from the traffic accident by Leonard McCoy, allowing her to continue striving for her goals of world peace, which ultimately delays the the United States of America' entry in World War II. As a result of these actions, Germany was allowed to complete its heavy water experiments and permitted them to be first in developing of the atomic bomb. This, together with the V-2 rocket, enabled Germany to capture the world. (TOS: "The City on the Edge of Forever")
