Franklin Roosevelt actually said...

"May you get back home to our good America just as soon as you can."

"I wish that great numbers of our people could see this work of getting the necessary equipment and supplies through to our ally."

"Apart from winning the war, I want to tell you that you—all of you—individually and collectively, are a part of that purpose."

"America is proud of you, proud of what you are doing in this distant place."
