To answer the questions in the two links you provided.
In the first one, your source assumes that the 9/11 commission finding contacts is the same as having a close relationship. I've had some contacts with Tony Gwynn, but I wouldn't say we're close. Since we only met once and all the interest was coming from my side. The same thing applies here. There was "no collabrative relationship." If you rely on the Media Research Center for your unbiased news, then I don't know how to talk to you.
The reason the 2nd link isn't getting more airtime is because both Russia and the United States say - clearly in your article - that the information Russia had was far too vague to justify war. They said it and we said it. Considering how shaky our justification was in the first place, I can't imagine how vague this information was.
In the end, your examples give more of a view of your bias than the media's bias.
