Going through the shelves in this house is always an adventure. When poking through the shelves, deciding which of my text books to take upstate, I happened across the Kerr Home Canning Book (1943) which I believe came to us via David's mother's estate. (How the book got co-mingled with Curtis's Matrix Groups, Fleming's Functions in Several Variables, Toni Morrison's Beloved, and Anthony Wallace's Death and Rebirth of the Seneca I'm not sure, but such are the shifting geological strata of David's office shelves.)
The book features this interesting head-quote from Franklin Roosevelt on the weaponization of food:
Food is no less a weapon than tanks, guns and planes. As the power of our enemies decreases, the importance of food resources if the United Nations increases. With this thought in mind, we must further mobilize our resources for the production of food.
How times do change.
(Of course, what is at issue is not just feeding "our" side, but starving out the enemy. Is it food, or starvation, that is the weapon?)
