Censorship in Iraq - is the US setting a censorial foundation?

The American government doesn't like what Iraqi satellite TV stations Al-Sharqiya, Al- Zawraa, and Saladdin TV and is attempting to close them down by either banning them or putting pressure on the satellite carrier, NileSat, owned by the Egyptian government. Apparently these channels have been showing footage the American and Iraqi government don't like and perceive as harmful to their interests. Al-Sariqiya's office was shut down and the Egyptian government has been asked to take Saladdin off its satellite because the stations are seen "as catalysts for sectarian tension and for "inciting hatred and instigating violence” in Iraq." And you know what, they probably are. But short of telling insurgents where to attack, for example, which would be speech classified as incitement, shouldn't the diversity of opinion be protected in the name of liberty? 

The reason I thought of this is that I just got through John Stuart Mill's classic treatise On Liberty a foundational text upon which many of our Western notions of liberty, free expression and the tyranny of the majority come from. For example, he specifically addresses the issue of free media and sectarianism. He writes that “the tendency of opinions to become sectarian is not cured by the freest discussion, but is often heightened and exacerbated thereby” and that people very often will end up rejecting the truth simply because it is “proclaimed by persons regarded as opponents.” But he goes on the say that the pernicious evil is less in the “violent conflict between parts of the truth”, that is these sectarian opinions, than in “the quiet suppression of half of it.” And the fact is, the sectarian violence wracking Iraq is the truth. There may be other parts of the truth, but no one would deny this is part of it. Is it possible to promote democracy while suppressing true freedom of speech? Can a democracy be built without the supporting infrastructure provided by institutions such as a free media, a functional legal system, and security forces loyal to the state who wield their power in the interest of public good rather than sectarian loyalty? If we start out censoring media do we build the Fourth Estate upon a foundation of censorship that will come back to haunt us in years to come? Can the noble institution of a free press emerge from such ignoble beginnings?
