USDA CIO Sam Berry says America's ability to feed itself is one of its biggest geopolitical advantages. "We are uniquely positioned as a country because we can feed ourselves. That is not the case for a lot of countries. China can minimally feed itself." "In warfare, agriculture and the food supply is usually hit before anything kinetic happens, even before the world knows it's warfare. So since you can impact a nation's food supply in the future, agriculture is a big deal."
