at the Center for Strategic and International Studies, and published over 200 articles and monographs on defense issues. Zakheim was then appointed as Under Secretary of Defense (Comptroller) from 2001 in George W. Bush administration, and served in the capacity until July 2004. During his term as comptroller, he was tasked to trace the Pentagon's 2.3 trillion dollars' worth of unaccounted transactions. He also played an active role in the Department's system acquisition, strategic planning, programming, and budget process. In 2008, he was appointed by President Bush as a member of the Commission on Wartime Contracting in Iraq and Afghanistan. He was succeeded by Tina W. Jonas as the top budget official at the DoD. Zakheim retired as a senior vice president of Booz Allen Hamilton in 2010. He is a senior fellow at the CNA Corporation and a senior advisor at the Center for Strategic and International Studies. He is also co-vice chair of Global Panel America with Malcolm Rifkind. His 2011 book, A Vulcan’s Tale: How the Bush Administration Mismanaged the Reconstruction of Afghanistan, discusses the Bush administration's missed opportunities and struggles to manage two wars, particularly the seemingly endless conflict in Afghanistan. Zakheim also sits on the Atlantic Council's board of directors. In the 2020 presidential election, Zakheim, along with over 130 other former Republican national security officials, signed a statement that asserted that President Trump was unfit to serve another term, and "To that end, we are firmly convinced that it is in the best interest of our nation that Vice President Joe Biden be elected as the next President of the United States, and we will vote for him."
