This was the 1941 State of the Union Address, but is commonly known as, "The Four Freedoms Speech." In it, FDR laid out his vision for what the Allies stood for against Germany, Italy, and Japan.

The four freedoms he wanted to fight for were: 1) freedom of speech, 2) freedom of religion, 3) freedom from "want," or material deprivation and poverty, and 4) freedom from fear of national invasion and dictatorial regimes.

"Four Freedoms" precedes the Lend-Lease act by about three months, and one can already see the inklings, the sparkles, oh, the basic sentiments that point to FDR's intentions for foreign policy in the near future. In this SotU Address, he is basically prepping the public for what is to come by appealing to their sympathies for moral goodness, coupled with American-style freedom, while warning them of the threat to this wholesome way of life.

In this way, no one's forced to deny isolationism, but everyone is made to consider how much they value the benefits of democracy and recognize the necessity of defending it. As a result, FDR created a scenario in which Lend-Lease could actually come into being with successful implementation and an understanding, if not full approval, of the American people.
