The theory of independence is as old as man himself, and it was not invented in this hall. But it was in this hall that the theory became a practice; that the word went out to all, in Thomas Jefferson's phrase, that "the God who gave us life, gave us liberty at the same time." And today this Nation - conceived in revolution, nurtured in liberty, maturing in independence - has no intention of abdicating its leadership in that worldwide movement for independence to any nation or society committed to systematic human oppression.
