Jack Goldsmith’s interview with Jefferson Powell on his new book, Targeting Americans: The Constitutionality of the U.S. Drone War. The interview focuses on the legal debate surrounding drone strikes, the use of which has expanded significantly under the Obama Presidency as part of the continuing war against terror. Despite the political salience of the legal questions raised by targeted killing, the author asserts that there has been remarkably little careful analysis of the fundamental legal question: the constitutionality of the policy.
