Buffett's father, Howard Buffett, was perhaps the most libertarian congressman in U.S. history.

He was also a vehement opponent of foreign military intervention, including military aid:

"Even if it were desirable, America is not strong enough to police the world by military force. If that attempt is made, the blessings of liberty will be replaced by coercion and tyranny at home. Our Christian ideals cannot be exported to other lands by dollars and guns. Persuasion and example are the methods taught by the Carpenter of Nazareth, and if we believe in Christianity we should try to advance our ideals by his methods. We cannot practice might and force abroad and retain freedom at home. We cannot talk world cooperation and practice power politics."
