Sparkle,
I think what you'll find if you read some of the 'anti-Iraq' war posts on here, is that a lot of MAPers are, as Koyo so eloquently put it, not 'anti-Iraq' but 'anti-unjust-war'.
If you read closely, you will see that the majority of those posts are sympathising with and supporting the troops, but questioning the reasons for them being there in the first place.
What you have are good men and women, placed in a dire and unassailable situation, against massive odds, with no real purpose or reason to fight. These troops then get seen by the very people they are supposedly there to help as 'invaders'. How long can anyone put up with that sort of thing before it all goes a bit screwy?? Get treated like a villain long enough, and eventually you'll start to believe you are one.
And the bit that really galls is that if American's learned to loook at their own history they would see that this sort of situation only ever ends in a massive loss for the invading forces! Hell, the Yanks only have about 200 years worth, it's not like it's a lot to remember!! (Sorry, low blow, but it really drives me nuts!)
My problem with the whole situation is that the troops flat-out shouldn't be there. We went in on a pretence, with a purpose that was a sham, and now having failed in that we are still there. Why? Why are troops serving and dying in a war that shouldn't have happened in the first place? Reason: Money. Plain and simple.
I will join Koyo in saying I'm not anti-Iraq, I'm anti-good-people-dying-to-make-others-richer.
And kudos to you for joining up, all I'll say is watch your back man, and try to get out clean!
As to your original question - easy. Yes, images and clips like those you describe could stir up a lot of support for the troops serving out there, or they could have the opposite effect and actually pour petrol on the anti-war fire. And that's why they aren't being shown. The high-ups are unsure of how people would react, and before you start spreading propaganda, you need to know it will send the right message.
