There, he edited and contributed to Technology and Naval Combat in the Twentieth Century and Beyond (2001), which focussed on technical changes in making naval policy, and The Anglo-Japanese Alliance, 1902-1922 (2004) which was based on papers given at the Anglo-Japanese Alliance 1902 Centenary Conference in 2002.

In 2015, O'Brien published How the War Was Won: Air-Sea Power and Allied Victory in World War II (2015), which was described by Talbot C. Imlay in The Journal of Modern History as "provocative" and "revisionist history at its best". After an analysis of the proportion of military output devoted to the different arenas of combat, O'Brien concluded that victory in World War Two was determined not through battles on land, but in the air and at sea on what he calls an "Air-Sea Super Battlefield" that crossed thousands of miles. O'Brien argues that securing dominance in this battlefield enabled the Allies to degrade the ability of the Axis powers to wage war by destroying their ability to manufacture equipment or by destroying it in transit to the battlefield before it could be put into use. The degrading of Axis aircraft production also had the effect of denying air-support to Axis land forces, leading to more defeats for them on the ground. , Harry S. Truman, Joseph Stalin; and back: Leahy, Ernest Bevin, James F. Byrnes and Vyacheslav Molotov. In 2019, O'Brien published ''The Second Most Powerful Man in the World: The Life of Admiral William D. Leahy, Roosevelt's Chief of Staff'', in which he discussed Leahy's influence on major U.S. decisions during the Second World War through the lens of his relationship with U.S. president Franklin D. Roosevelt. Examples included the decision to give equal or even higher priority to the fight against Japan rather than Germany, and Leahy's opposition to a 1943 Allied invasion of Europe. The book then goes on to discuss the more difficult relationship between Leahy and president Harry S. Truman in the post-war era in the context of Leahy's non-interventionist inclinations. Craig L. Symonds in Historynet.com noted that O'Brien credited Leahy with far more influence than Henry H. Adams had in his 1985 biography of Leahy, Witness to Power, but was forced to rely too much on circumstantial evidence due to a lack of primary sources for Leahy's role. Matthew Wayman in Library Journal described the book as an excellent biography of a significant but neglected figure in World War II history, but noted the lack of any significant criticism of the subject. Steve Donoghue in The Christian Science Monitor, welcomed the book as an overdue first-rate telling of the life of a man who had more authority than celebrity and who was the "quiet commander in the background of every photo" of Roosevelt. ==Selected publications==
