From a letter from F.D.R. to the British Government, Dec. 9th, 1941
There is no question in my mind that if we summon our resources, both our leadership resources and all of the tools at our disposal, not just military force, which should be used as a last resort, but our diplomacy, our development aid, law enforcement, sharing of intelligence in a much more open and cooperative way—that we can bring people together.
But it cannot be an American fight. And I think that we will support those who take the fight to Hitler. That is why we have troops in France that are helping to train and build back up the French military, why we have special operators in Italy working with the Sicilians, so that we can be supportive.
But this cannot be an American fight, although American leadership is essential.*
Franklin Delano Roosevelt
P.S. Good luck with the whole "D-Day" thing.
