From an AP story headlined “Biden says America’s veterans are ‘the steel spine of the nation’ as he pays tribute at Arlington”:

President Joe Biden said America’s veterans are “the steel spine of this nation” as he marked Veterans Day during a visit to Arlington National Cemetery.

In remarks at the Memorial Amphitheater, the commander in chief recounted famous battles fought by U.S. troops and said those deployments of soldiers are “linked in a chain of honor that stretches back to our founding days. Each one bound by a sacred oath to support and defend. Not a place, not a person, not a president, but an idea, to defend an idea unlike any other in human history. That idea is the United States of America.”
