How much our vaunted Civilization rests upon the thin security provided by the shielding roofs over our man-made "Cartwright Machines" is made particularly clear during war.
Then those carefully hand-washed machines, the ones we normally baby and only take for a spin in good weather on a summer's afternoon , are worked to death in all times of year and in all kinds of weather.
As a result, they, their human operators and the civilizations behind them usually crack up pretty quickly.
We have all seen those terribly despondent photos of the soldiers of some Great Power or other, desperately trying to get all their vehicles out of the mud of Russia's winter or Guadalcanal's summer ; Civilization spinning its wheels hard and going nowhere fast.

Just like clockwork......
