Our responsibility is not discharged by an announcement of virtuous ends. Our responsibility is to achieve these objectives with social invention, with political skill, and executive vigor. I believe for these reasons, that liberalism is our best and our only hope in the world today.

John F. Kennedy (1917–1963) American politician, author, journalist, US President (1961–63)
