The Quarantine Speech
given by U.S. President Franklin Delano Roosevelt
on October 5
calling for an international "quarantine of the aggressor nations" as an alternative to the political climate of American neutrality and isolationism that was prevalent at the time. The speech intensified America's isolationist mood, causing protest by isolationists and foes to intervention. The speech was a response to aggressive actions by Italy
, and suggested the use of economic pressure, a forceful response, but less direct than outright aggression.
