True, British parlament was the prime example of modern legislation.
It was the fact that world super powers at the time (U.S) and (U.S.S.R) where building up an armory of nukes but they both knew if they where to use these weapons it would utterly destroy the world.
Here's a memory aid: (U.S): hey Russia lets not kill each other with nukes in this war lets just keep it "COOL" and spy on each other instead
What was known as "The War Department" had a period of existence from August 7, 1789, in its early origins, it was also named the "War Office" during the revolution; and it was located in Philadelphia, and then moved to Washington D.C. in the early 1800s.
It was led by "The Secretary of War" who was member of the United States President's Cabinet, starting with George Washington's administration, until September 18, 1947. At this point, it got divided into Department of the Army and Department of the Air Force coming together to the Department of the Navy conforming the new "National Military Establishment" (NME), and in 1949 was renamed "the United States Department of Defense".
Hello....
