Part of the reason for the ridiculous corn subsidies is so if the whole rest of the world ends, the US will still have enough food. We'll have to stop eating some specific foods (like we export chicken dark meat to China and they send the breast meat to us), but in terms of overall calories the US will be fine. Domestic distribution is a bigger worry, quarantines or just plain shops shutting down.
