U.S. military protocol requires troops to salute the commander in chief.
But the practice of a president returning that salute, which is not required, is thought to have started with Ronald Reagan.
A long-running debate has questioned whether it’s appropriate for a civilian president to salute members of the military.
Casual saluting styles have also been criticized. (George W. Bush was once pictured returning a salute while holding his dog Barney, and Barack Obama created a stir when he saluted while holding a coffee cup.)
As for a president saluting foreign troops, it is customarily a sign of respect toward friendly nations, which generated questions last year after Mr. Trump returned the salute of a North Korean military officer.
That’s it for this briefing.
Hope you’re in the right place, even if it’s the wrong time.
