Thank you for posting this. Very few images rouse my patriotic emotions, but that one did.
Another that made the rounds after September 11th was this one:
I posted it on the office bulletin board on September 12th, shortly before I retired. My boss took it down saying the image dishonored the American flag. That may technically be true but somehow, I believe exceptions should be made under extreme circumstances.
I happened to visit the old office some 10 years later and saw one of the younger employees had framed the picture and put it on the wall. Brought tears to my eyes.
Maybe there is hope for the younger generations after all.
