On May 13, 2007, Bacevich's son, also named Andrew J. Bacevich, was killed in action in Iraq by a improvised explosive device south of Samarra in Salah Ad Din Province. The younger Bacevich, 27, was a First Lieutenant. He was assigned to the 3rd Battalion, 8th U.S. Cavalry Regiment, 1st Cavalry Division.
Bacevich also has three daughters.
On August 15, 2008 Bacevich appeared as the guest of Bill Moyers Journal on PBS to promote his new book, The Limits of Power. As in both of his previous books, The Long War (2007) and The New American Militarism: How Americans are Seduced by War (2005), Bacevich is critical of American foreign policy in the post Cold War era, maintaining the United States has developed an over-reliance on military power, in contrast to diplomacy, to achieve its foreign policy aims. He also asserts that policymakers in particular, and the American people in general, overestimate the usefulness of military force in foreign affairs. Bacevich believes romanticized images of war in popular culture (especially movies) interact with the lack of actual military service among most of the population to produce in the American people a highly unrealistic, even dangerous notion of what combat and military service are really like.
Bacevich conceived The New American Militarism not only as "a corrective to what has become the conventional critique of U.S. policies since 9/11 but as a challenge to the orthodox historical context employed to justify those policies."
Finally, he attempts to place current policies in historical context, as part of an American tradition going back to the Presidency of Woodrow Wilson, a tradition (of an interventionist, militarized foreign policy) which has strong bi-partisan roots. To lay an intellectual foundation for this argument, he cites two influential historians from the 20th century: Charles Beard and William Appleman Williams.
Ultimately, Bacevich eschews the partisanship of current debate about American foreign policy as short-sighted and ahistorical. Instead of blaming only one President (or his advisors) for contemporary policies, Bacevich sees both Republicans and Democrats as sharing responsibility for policies which may not be in the nation's best interest.
In March 2003, at the time of the U.S. invasion of Iraq, Bacevich wrote in The Los Angeles Times that "if, as seems probable, the effort encounters greater resistance than its architects imagine, our way of life may find itself tested in ways that will make the Vietnam War look like a mere blip in American history."
In an article of the The American Conservative dated March 24, 2008, Bacevich depicts Democratic presidential candidate Barack Obama as the best choice for conservatives in the fall. Part of his argument includes the fact that "this liberal Democrat has promised to end the U.S. combat role in Iraq. Contained within that promise, if fulfilled, lies some modest prospect of a conservative revival." He also goes on to mention that "For conservatives to hope the election of yet another Republican will set things right is surely in vain. To believe that President John McCain will reduce the scope and intrusiveness of federal authority, cut the imperial presidency down to size, and put the government on a pay-as-you-go basis is to succumb to a great delusion."
