Here is one thing about the US , during WW2 , we were able to not only feed our own population , but we were also feeding all of our allies as well , and we were not even going full bore , all that at a time when todays agricultural advancements and knowledge didnt exist . Never underestimate a pissed off , hungry , broke population with guns . Why do you think they are trying so very hard to disarm Americans ? Because they are scared ……….plain and simple . They may put on the show of the all powerful , invincible state , but its a show , push comes to shove , the population will win .
