Roosevelt gets too much respect. No telling how many he condemned to die or lose property, including Americans or persons residing in South America that were interred or sent to Germany.
In 1938, US President Franklin Roosevelt called for a conference to be held in Evian, France, to discuss the increasing number of people leaving Germany. Thirty-two countries sent delegates to the conference, and all but one country the Dominican Republic agreed to refuse any further German refugees. From that point forward, it no longer mattered whether conditions in Germany worsened—many of the people who were at risk were then trapped.
