They actually were spoken five years before his birth. On February 9, 1941, Winston Churchill, said about the passage of the Land-Lease Act:
"Put your confidence in us. Give us your faith and your blessing, and, under Providence, all will be well. WE SHALL NOT FAIL OR FALTER; WE SHALL NOT WEAKEN OR TIRE. Neither the sudden shock of battle, nor the long-drawn trails of vigilance and exertion will wear us down. Give us the tools and we will finish the job."
And so the job was finished in less time than Bush's war in Iraq.
