The Ordinary Everyday Christian blog has the American and British public response to the attack posted.
Roosevelt: "Always will we remember the character of the onslaught against us. No matter how long it may take us to overcome this premeditated invasion, the American people in their righteous might will win through to absolute victory."
Churchill: "There shall be no halting, or half measures, there shall be no compromise, or parley. ...Only when the earth has been cleansed and purged of their crimes and their villainy shall we turn from the task which they have forced upon us, a task which we were reluctant to undertake, but which we shall now most faithfully and punctiliously discharge."
