US Presidency
1941

And what we have learned is this: There is no such thing as security for any nation, or any individual, in a world ruled by the principles of gangsterism. There is no such thing as impregnable defense against powerful aggressors who sneak up in the dark and strike without warning. We have learned that our ocean-girt hemisphere is not immune from severe attack, that we can not measure our safety in terms of miles on any map any more. We may acknowledge that our enemies have performed a brilliant feat of deception, perfectly timed and executed with great skill. It was a thoroughly dishonorable deed, but we must face the fact that modern warfare as conducted in the Nazi manner is a dirty business. We don't like it, we didn't want to get in it, but we are in it and we're going to fight it with everything we've got. I do not think any American has any doubt of our ability to administer proper punishment to the perpetrators of these crimes.
