The Great Depression caught a great many people off guard.  The people were unhappy with Hoover's "Do Nothing" stance.  They voted him out and brought in Roosevelt who immediately went to work instituting socialist changes to a capitalist based economy.  Seems the people were desperate for anything that promised change.  Roosevelt began by gutting an already skeletonized military and then funneling that money into his many other projects.  It was a dangerous gamble.  War was already clearly looming on every horizon.  He had involved the U.S. with war against Japan -- in China with the American Volunteer Group (AKA the Flying Tigers) and against Germany both in Spain with the Lincoln Brigade and later in England with the Lend Lease Act and the Eagle Squadron.

One of the many things Roosevelt did, was to assign a young Lt.Col. named Eisenhower to the Chief of Staff's office and then tasked him with researching how much effort, time and money it would take to convert civilian peace time production into war time, weapons production -- a great clue about Eisenhower's farewell address at the end of his presidency and his clearly stated warning about lobbyists in Washington and the war making industry...

Yes, the Depression dragged on until the U.S. officially entered the war.
