Educate others to grow our base of informed citizens, it's tyranny. Spread the Gospel.
Prepare wisely individually. An army runs on it's stomach.
Network with those who prepare wisely and take advantage of the strength in numbers and the economy of scale.
Then, when the curtains come down and the truth is evident to an informed citizenry, we unite and fight the new world order.
