Here's a hypothetical for you. You and your best friend are sitting in your living room and in comes a criminal to harm you and your family. You do not have a gun but your best friend does and he turns to you and say's I'll help you get rid of this guy but you owe me for the rest of your life. Is this right?
Hi Graham,
The analogy that was actually bandied around at the time was the 'fire extinguisher' one, coined by one of Roosevelt's advisers;
"It seems to me that we Americans are like the householder who refuses to lend or sell his fire extinguisher to help put out the fire in the house that is right next door."
However, Anti-interventionist Senator Burton Wheeler countered this logic with;
.."you can't put your shirt-tail into a clothes wringer and pull it out suddenly while the wringer keeps turning."
Roosevelt sought a solution (Lend Lease), and refashioned the above analogy thus;
His new idea would get…"rid of the silly, foolish old dollar sign" proposing that the USA should lend its garden hose to help his neighbour put out his fire-and if the hose were damaged there would be "a gentleman's obligation to repay in kind."
(From 'The Most Unsordid Act': Lend-Lease, 1939-1941 by W.F. Kimball 1969.)
Have you read much on the Canadian Mutual Aid?
