Prayer for dummies

Funny post by Pharyngula on the power of prayer.
Pharyngula: Prayer for dummies

In WWII, there was an advisor to Churchill who organized a group of people who dropped what they were doing every night at a prescribed hour for one minute to collectively pray for the safety of England, its people and peace. This had an amazing effect as bombing stopped.
And the brave pilots of the RAF, radar, cracking of the German codes, the shipment of war material across the Atlantic, the reorganization of anti-aircraft defenses, and the morale of the British people, etc., had nothing to do with it? A one minute prayer each night is going to get credit for England’s survival in the war?
So why didn’t England just ditch the other nonsense and set up non-stop prayer brigades? They could have prayed Germany right back into the Stone Age. Oh, and weren’t the German people praying for their pilots?
