The problem in defense is how far you can go without destroying from within what you are trying to defend from without.
Eisenhower, Dwight D.
They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.” – Benjamin Franklin Historical Review of Pennsylvania 1759
“You and I are told we must choose between a left or right, but I suggest there is no such thing as a left or right. There is only an up or down. Up to man’s age-old dream — the maximum of individual freedom consistent with order — or down to the ant heap of totalitarianism. Regardless of their sincerity, their humanitarian motives, those who would sacrifice freedom for security have embarked on this downward path.” – Ronald Reagan
“To announce that there must be no criticism of the president, or that we are to stand by the president right or wrong, is not only unpatriotic and servile, but is morally treasonable to the American public.” – Theodore Roosevelt (1918)
“During times of universal deceit, telling the truth becomes a revolutionary act.” – George Orwell
“If ye love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you, and may posterity forget that ye were our countrymen.” – Samuel Adams, speech at the Philadelphia State House, August 1, 1776.
