No, the US will not depend on foreign aid to [primarily] feed it's citizens. Never going to happen.

You've got it backwards - foreign aid using US grown crops provides increased very stable demand. Take any excess grains made in a given year and ship them to another country, the farmers get paid well for it so they keep their productive capacity high, and the marginal cost of getting it to a charity overseas is low anyway. This means there's always enough grain to feed our citizens.
