Cut off the water supply to any city and it dies shortly there after. Cut off the food supply and it usually takes a month for the city to die. Cut off all escape and supply lines and it decends into panic in less than 24 hours.
I believe there are many like you. But I cannot 100% trust a military controlled by a corrupt Government.
I would worry more about DHS and their "Civilian Army" than the Military. Remember most civil rights abuses (The Civil War and Kent States being the exceptions to the rule) in the history of this country have come from the hands of the Civilian police forces.
