Why weapons crucial to the war in Ukraine are in short supply

Of all the assistance America has provided to Ukraine, the gift of 5,500 or so Javelins has been perhaps the most welcome.

Little wonder, then, that the Javelin has acquired exalted status among Ukrainians, celebrated in music and paintings (an image of the Virgin Mary holding a Javelin has gone viral).
