Wilson was also an outspoken critic of US Cold War policies. He refused to pay his federal income tax from 1946 to 1955 and was later investigated by the Internal Revenue Service. After a settlement, Wilson received a $25,000 fine, rather than the original $69,000 sought by the IRS. He received no jail time. In his book The Cold War and the Income Tax: A Protest (1963), Wilson argued that as a result of competitive militarization against the Soviet Union, the civil liberties of Americans were being paradoxically infringed under the guise of defense from Communism. For those reasons, Wilson also opposed involvement in the Vietnam War.
