His public commentary has appeared in several periodicals such as The Daily Telegraph and The Spectator. Roberts himself is possibly best known internationally for his 2009 non-fiction work The Storm of War, which covers historical factors of the Second World War such as Hitler's rise to power and the organisation of Nazi Germany. The book has been lauded by several publications such as The Economist, and it additionally received the British Army Military Book of the Year Award for 2010.
Elsewhere, his work has sometimes been criticised by, for example, The Economist who described one book as "a giant political pamphlet larded with its author's prejudices, with sneers at those who do not share them and with errors". However, much of Roberts' work, including his 2018 biography of Winston Churchill, has been widely praised; the Sunday Times, for example, called the Churchill biography 'Undoubtedly the best single-volume life of Churchill ever written.
