We’ll be alright. We handled it in 2022 when Russia (who is helped and supported by Iran by the way) invaded Ukraine. The world didn’t end when gas prices were crazy high then, we just kept chugging along.
We're the number one oil and gas producing country in the world. Nobody is concerned about whether or not the United States can grow food or fertilize it. At a higher cost? Yea maybe. Oh well - the alternative is unacceptable.
Food production will decrease, and even moderate increases in food prices mean many people unable to afford enough food.
