Michael Fullilove, head of the Lowy Institute, has written about President Roosevelt and the men who helped him to guide the US so reluctantly into World War II. Dennis Altman reviews this model of academic research.

It is ten years since the invasion of Iraq by the United States and the few countries willing to join it. Happening to be in Washington in February, and recalling worldwide protests in 2003, I was struck by what seems to be American amnesia about the war and its consequences. At least in Australia groups are exploring ways to prevent such catastrophic expeditions in the future. Even as Afghanistan follows Iraq towards a similar conclusion, the US government’s war mentality is kept alive by contestation with China, eyeballing of North Korea, countdown over Iran, nervousness about Syria, demands for more military spending, and war hunger in sections of the media. Americans’ nerves are further strained by domestic threats like cyber-infiltration, extreme weather, and mass killings, against which conventional defences seem powerless. Past wars don’t end all wars.
