World War II
A true world war, SIGINT still tended to be separate in the various theaters. Communications security, on the part of the Allies, was more centralized. Given that there were three major Axis powers, each primarily operating in a subset of the theaters, it is convenient to look at SIGINT from a primarily theater standpoint. From the Allied perspective, the critical theater-level perspectives were the Ultra SIGINT against the Germans in the European theater (including the Battle of the Atlantic, the Mediterranean Theater of Operations, and MAGIC against the Japanese in the Pacific Theater and the China-Burma-India theater. Germany enjoyed some SIGINT success against the Allies, especially with the Merchant Code and, early in the war, reading American attaché traffic. Japan was the least effective of the major powers in SIGINT. In addition to the official Allies and Axis battle of signals, there was a growing interest in Soviet espionage communications, which continued after the war.
British strategic stations were located at places including Darwin, Australia, and a Russian site. Major postwar stations include RAF Menwith Hill and Cyprus.

Famous quotes containing the words world and/or war:
“Children belong in families, which, ideally, serve as a sanctuary and a cushion from the world at large. Parents belong to society and are a part of that greater world. Sometimes parents are a channel to the larger society, sometimes they are a shield from it. Ideally they act as filters, guiding their children and teaching them to avoid the tempting trash.”
—Louise Hart (20th century)
“Many of our German friends before the war would come as our guest to hunt wild pig. I refused to invite Goering. I could not tolerate his killing a wild pig— seemed too much like brother against brother.”
—Joseph L. Mankiewicz, U.S. director, screenwriter. Joseph L. Mankiewicz. Countess (Danielle Darrieux)
