“How does something immoral, when done privately, become moral when it is done collectively?”
1980s, All It Takes is Guts: A Minority View (1987)
Context: How does something immoral, when done privately, become moral when it is done collectively? Furthermore, does legality establish morality? Slavery was legal; apartheid is legal; Stalinist, Nazi, and Maoist purges were legal. Clearly, the fact of legality does not justify these crimes. Legality, alone, cannot be the talisman of moral people.

1980s, Second term of office (1985–1989)
Context: Americans … are not going to tolerate intimidation, terror and outright acts of war against this nation and its people. And we are especially not going to tolerate these attacks from outlaw states run by the strangest collection of misfits, Looney Tunes and squalid criminals since the advent of the Third Reich … There can be no place on earth where it is safe for these monsters to rest, or train or practice their cruel and deadly. We must act together – or unilateraly, if necessary – to ensue that these terrorists have no sanctuary, anywhere.
