“The history of failure in war can almost be summed up in two words: too late.”
Douglas MacArthur (1880-1964)

He was Chief of Staff of the US Army during the 1930s and played a prominent role in the Pacific Theatre of War during World War II.

A pithy statement and truism, but meaningless without any context.
