I gotta say, it's just kinda weird to watch a grown man put on costumes and parade around with real heroes:
He's being a creep, really.
Central to American military tradition is the understanding that the military is under civilian authority, and at the head of that civilian authority is the President as Commander in Chief.
I believe the only time in American history a sitting President wore a military uniform was in 1794, when President George Washington put on a uniform and rode with militia to put down the
Whiskey Rebellion. Since then, even Presidents who entered the White House after a professional military career (e.g., Grant, Eisenhower) never wore a uniform
or anything suggestive of a uniform while serving as President. Certainly other wartime presidents -- Lincoln, Wilson, Roosevelt -- didn't strut around in uniforms. Nor did Presidents who had distinguished military service -- Kennedy, Carter, and even Bush's own father.
Heads of state of banana republics, or totalitarian dictators, swagger around in military uniforms. Saddam. Quaddafi. Noriega. Kim Jung-Il.
Not Presidents of the United States.
It's just wrong.
