It all goes to motivation and perspective. This Italian reporter is anti-Iraqi War/Anti-U.S. She's going to phrase everything she says and does in that context because she feels that she is right. She doesn't see the kidnappers as the bad guys, she sees the US as the bad guys because we "forced" the kidnappers into taking these actions. CBS wants to air the story because (I believe) many at that network agree with that view point to one degree or another. I would say that they just want to report on the news, but they would have known that based on previous interviews she would be blaming the US, and they would have offered a stronger rebuttal.
As for Jane Fonda, she's got a souring career and a new movie coming out that she's hoping will re-energize it. If the movie flops, so does she, so she's out trying to drum up support for herself - hence all of the "oh wo is me" stories that she's dishing out. I think she also believes that apologizing for sitting on the AA gun will win her some points, and I'm sure she actually believes that even though I don't thin it got her anywhere.
So I'm sure there are a lot of people at CBS who actually believe that there are now some Americans who have re-thought their positions on the war and the Pentagon's tactics, and who now thinkk that Jane Fonda is a pathetic creature who now needs our support. The abd thing is that I'm sure they are right in a few cases, but I think that most people saw through the BS.
