To me it looked like the authors tried to express some of their true thoughts, but were often forced to change or include parts into the script to reflect a more positive America, that really stood out.
I'm not stating flat out you're wrong, but do you have any actual evidence of parts they were "often forced to change?" Isn't it possible they included pro-American material because they didn't necessarily have a completely negative point of view about the US and the military? Not every opinion that America is less than evil necessarily has to be propaganda.
@krapp thanks for asking. I have no real evidence, except that he worked closely with military and you cannot be against your feeding hand. See interview: http://www.youtube.com/watch?v=iF6hOMY2vxA So obviously he is pro USAF, but that didn't mean he needed to portray the US Government in a good light in StarGate SG-1. He showed the USAF in a very good light though. He also supports the Greenpeace (Sea Shepard) and Charity.
