Explaining his move to rename the U.S. Department of Defense to the Department of War, as it was known before 1949, President Donald Trump explained it had "a stronger sound."

It offered better messaging, too. "Defense is too defensive; we want to be offensive too," he said.

The once and future Department of War would revive the spirit of the years when "we won everything."

Trump's language -- and the logic behind it -- demonstrates how little America's current leaders have learned from the clear failures of their predecessors across 70 years.
