Brief Summary
The Set-Up
After Germany goose-stepped all over Europe and crushed France, President Franklin D. Roosevelt got nervous that they (or another Axis power) were coming for the United States. He uses the opportunity of his third SOTU address to scare the bejeezus out of Americans and prepare them for possible war.
The Text
European nations were falling like dominoes to the tyrannical powers of Germany and Italy, so FDR employs his 1941 SOTU address to warn Americans of the possible military threat headed their way.
He references military conflicts of the country's past to highlight the unusually frightening circumstances of World War II…and coax people out of their complacent, isolationist mindsets.
FDR also demonizes the Axis powers (not that they need much help in the demonizing department) and their agenda to rule the planet. In doing so, he makes the situation seem really, really real (again, because it was). The message: the United States needs to be prepared because its democracy is under threat just like that of other countries in Europe.
P.S. They need America's help.
After a bit more fear-mongering, FDR expresses confidence in the integrity of the American people, but he again calls for a realistic perspective on the country's ability to defend itself and its values...especially in the event that the United States is the only democratic power left standing.
He suspects that spies and espionage will be the enemy's main method of infiltration (boy, was he wrong), and he delivers a series of requests to mobilize U.S. defenses. He also asks permission to end the policies of neutrality in order to assist other countries that are fighting the Axis and need help in the form of war materials.
In conclusion, he offers a vision of the future in the form of the Four Freedoms, where everyone everywhere enjoys a higher standard of living. These are the freedoms of speech and religion, and the freedoms from want and fear.
The fifth freedom, fun, never made it into the final draft…because FDR was stuffy like that.
TL;DR
Dear America,
Things are about to get infamous, so it's time to batten down the hatches, make more guns than we know what to do with, and be prepared to fight, fight, fight for democracy until the war is won.
XOXO, FDR
