Communism has never come to power in a country that was not disrupted by war or corruption, or both.

There is always inequality in life. Some men are killed in a war and some men are wounded and some men never leave the country. Life is unfair.

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]

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

I look forward to a great future for America - a future in which our country will match its military strength with our moral restraint, its wealth with our wisdom, its power with our purpose.
