1. Our national Anthem has been part of sporting events for many decades. Today games in the NFL begin with the NA and many times with our flag displayed by scores of service personnel, a flag stretching from side line to side line and covering 60% of the fields length; all this followed up by a fly over of fighter jets at low altitude. In baseball the seventh inning was once a time to stretch, now it's a time to hear "America the Beautiful"; a big controversy arose over the current president not wearing a flag pin or raising his had over his heart when "America the Beautiful" played.
Many times a fair assessment of American foreign policy deserves to be questioned and debated, but such discourse is stifled by the cry from the right wing that to do so is un-American.
Flag display in the background of most politicians making national addresses is common, but George W. Bush was the first POTUS to appear in a military uniform on the day he declared "Mission Accomplished".
I hate to say it, but it seems to me that you are looking too hard for "similarities" and thus seeing what you concluded from the outset. You might be better served looking for differences and then running through the list and seeing what is left over.
I've chosen to only look at one point this time - the first point, though several others might serve as well for this example.
Baseball is arguably the most conservative sport in the USA; it is losing young audience to "Xtreme" sports and has an increasingly elderly demographic. Thus it is hardly surprising that they are using flag waving and other appeals to appeal to what has become their target demographic. I'm certain that if they believed they would get more money by having Paris Hilton (with apologies in advance to Ms. Hilton) mangle the national anthem while letting her dress slip and expose a nipple, or the slit in her skirt be high enough that a quick turn revealed she had chosen not to wear undergarments, then she might appear at every game.
A walk around my neighborhood shows ONE flag flying, I reached 200 houses before I stopped counting which did not have a flag, and I live in Texas a bastion of conservatism. I had a teacher once who had been a young girl in Nazi Germany; Hitler Youth was like the Scouts - every child belonged to it, every house flew a German flag, and everywhere you went there was something put up to glorify Hitler, exhort greater effort for the war, or remind readers to watch everyone for seditious behavior. Not a few signs here and there, but every single street corner.
Stifling opposition goes back to Hamilton in the US, and I recall a lot of discourse about the problems in the Bush administration. I sent a letter to the White house warning them they were making a strategic error in moving against Iraq (because it exhausted our last reserves of troops, everything was in the field at that point and any true emergency would have seen us stretched too thin for a timely response) - and if I got no return letter, I also did not get brown shirted goons showing up to arrest me for treason in suggesting the president made an error.
As for politicians wrapping themselves in the flag - that's as old as politicians and flags. Andrew Jackson capitalized on his military past, repeatedly bringing up the Battle of New Orleans, but that hardly makes him a fascist does it? JFK turned his status as (legitimate) war hero (ever hear of a book called PT 409?) into a political career.
Bush Junior had no legitimate military past, but wanted to avoid the doubts (of military people) which plagued the pot smoking draft dodging POTUS which had been Clinton.
Slightly OT - Bush Junior and Clinton were both travesties as presidents. Clinton's claim about the economy was absolute nonsense - the internet revolution buoyed the economy despite, not because of, the actions of the Clinton Administration. After 9/11 Bush Junior got caught up in his military role and allowed everything to fall apart. So far Obama seems just another smarmy politician pushing his "goals" with a primary eye for getting re-elected. He needs aother technological economic miracle to avoid having the situation decline further. I doubt one is forthcoming. All this is naturally my view of things.
