Mankind must put an end to war before war puts an end to mankind.

Mankind must put an end to war, or war will put an end to mankind... War will exist until that distant day when the conscientious objector enjoys the same reputation and prestige that the warrior does today.

We're winning the war but we haven't won the war yet. I think whoever takes over this job in 20 years will still have to fight this fight.

Mankind must put an end to war - or war will put an end to mankind.

[Address before the United Nations, September 25 1961]

In a very real sense, it will not be one man going to the moon it will be an entire nation. For all of us must work to put him there.

We prefer world law in the age of self-determination to world war in the age of mass extermination.
