It's a fair point for sure. Wish I had links handy and I'll see if they can find solid references. My understanding is that a huge proportion of us crop production is in three or four crops and that most f that production is traded internationally. Meaning, we produce plenty of corn and a few others but we export that and still import a big chunk of my ur actual food supply (or at least the raw materials processed into our food supply).

I'm happy to be wrong there though it's been a while now since I went down that rabbit hole!
