Multiple realities
(covers information from several alternate timelines)
The Allies were a faction in World War II that fought against the Axis Powers, including Nazi Germany and Japan. The United States of America, Great Britain and France were members of the Allies.
In a holoprogram set in September 1944, Mademoiselle de Neuf argued to Katrine that a direct attack against the Nazi forces in Sainte Claire would be of greater assistance to the Allies than remaining hidden. Allied High Command was the Allies' military command in this program. (VOY: "The Killing Game")
In 1944 of an alternate timeline version of this war, Vosk threatened to give plasma cannons to the Allies, an act that would result in the destruction of Berlin, if the Nazis did not meet his demands. (ENT: "Storm Front, Part II")
