JFK: World Peace Does Not Require Love, Merely Tolerance

"World peace, like community peace, does not require that each man love his neighbor—it requires only that they live together in mutual tolerance, submitting their disputes to a just and peaceful settlement."

John Fitzgerald Kennedy (1917-1963) was the 35th President of the United States who served from 1961 until his assassination in 1963. Prior to his presidential election, Kennedy was a decorated veteran of World War II, U.S. Senator, and best-selling author. Despite his relatively short presidency, Kennedy is remembered for his exceptional oratory skill, political triumphs and mistakes, and ambitious dreams for a better tomorrow.
