I would have joined the marines out of high school if I could have. Sadly enough I've been a type1 diabetic since I was 8 and that option was taken from me accordingly. My father was a sergeant in the green berets during vietnam and my grandfather a private in the italian campaign during WWII. My family has greatly contributed to this country and I have contributed in a small way by applying (waiting for a response) to the peace corps and assisting my community in a small way through the masons. Please don't question my contributions. I consider myself a very supportive and patriotic american and I believe my actions have gone towards proving this.
I don't even see why you need to apologize quite honestly. Jokes and "herpderp hamburger-eatting machines" aside, America has been overall a positive force in the world. Yes, it has its faults. Yes, Iraq was a wrong war. Yes, attacking Iran will be idiotic, but if the US hadn't, for example, helped South Korea can you imagine how many more Koreans would suffer today? Or if the USA hadn't protected my country, Greece how much more in shit would we be today? (yes, I am not even joking). Or if the US hadn't entered the war and Russia had taken over mainland Europe and turned it all into "eastern block"?
The world would be a worse one today. Be proud of what you are.
