“The free world, at least dimly aware of these facts, has naturally embarked on a large program of warning and defense systems. That program will be accelerated and extended. But let no one think that the expenditure of vast sums for weapons and systems of defense can guarantee absolute safety for the cities and citizens of any nation. The awful arithmetic of the atomic bomb does not permit of any such easy solution. Even against the most powerful defense, an aggressor in possession of the effective minimum number of atomic bombs for a surprise attack could probably place a sufficient number of his bombs on the chosen targets to cause hideous damage.”

Context: The tank, the B-52, the fighter-bomber, the state-controlled police and military are the weapons of dictatorship. The rifle is the weapon of democracy. Not for nothing was the revolver called an "equalizer." Egalite implies liberte. And always will. Let us hope our weapons are never needed — but do not forget what the common people of this nation knew when they demanded the Bill of Rights: An armed citizenry is the first defense, the best defense, and the final defense against tyranny.
Abbey's Road (1979)

Context: It is impossible to use an atomic bomb here to defend the population of our own city. Likewise we cannot use our bacterial weapons here in our own country. These weapons of annihilation must be used offensively. And against their use no effective defense is possible.
