Fighting the Last War

An early version appeared in 1919 when Robert Blatchford wrote: "The ordinary statesman or military man is generally obsessed by bygone ideas and methods. He always prepares for the last war." The saying became frequently used during World War II in the 1940s. Though often attributed to Georges Clemenceau, this attribution came decades after earlier versions appeared. The phrase critiques military leaders who prepare for future conflicts using strategies from previous wars, failing to adapt to new technologies or changing circumstances.
