The people DO need liberating, but the US doesn't care about the people.
As I said before, Robert Mugabe has butchered white land owners, and because they were the farmers, his people now starve, the US did nothing.
King Jong Il, tortured his people inside pyongyang, the US did nothing.
Let's face it, this war sure as hell isn't about the people.
And, one other thing, I'm pretty sure I said before, Iraq is capable of meeting, and surpassing Saudia Arabia in oil production, their only limiting factor is their antiquated technology. Otherwise, they could export much more oil. And the US could get their hands on millions of barrels per day, for, relatively, next to nothing. It would also be a long term solution, any government in Baghdad would thereafter have strong ties with the US, and would continue to provide them with cheap oil for a long long time.
