More drones, cheap drones, quickly!

David Petraeus, the now-retired general who did so much to shape the US Army's war-fighting style in this century, urges us in today's Wall Street Journal to return to the 1940s, when we churned out weapons in huge quantities and at bargain prices. (Adjusted for inflation, a WW2 Jeep cost $14,818, a third of what you'd probably spend today.) Ukraine should be our model: while the Pentagon hopes to deliver a $100,000 loitering munition at some time in the future, Kyiv intends to build a million drones a year, costing between $300 and $1000.
