Foreign policy

While Walter Oi is credited with establishing the economic basis for a volunteer military, Friedman was a proponent, and was credited with ending the draft, stating that the draft was "inconsistent with a free society".

In Capitalism and Freedom he argued conscription is inequitable and arbitrary, preventing young men from shaping their lives as they see fit. During the Nixon administration he headed the committee to research a conversion to paid/volunteer armed force. Friedman did, however, believe the introduction of a system of universal military training as a reserve in cases of war-time could be justified. He still opposed its implementation in the United States, describing it as a "monstrosity".

Biographer Lanny Ebenstein noted a drift over time in Friedman's views from an interventionist to a more cautious foreign policy. He supported US involvement in the Second World War and initially supported a hard-line against Communism, but moderated over time. However, Friedman did state in a 1995 interview that he was an anti-interventionist. He opposed the Gulf War and the Iraq War. In a spring 2006 interview, Friedman said the US's stature in the world had been eroded by the Iraq War, but that it might be improved if Iraq were to become a peaceful and independent country.
