Oh, stop it about Iraq. The UN mandated the liberation of Kuwait, but did not have the foresight to allow the coalition to go after Saddam. The U.S. wanted to go to Baghdad to force an end to the crisis - the UN held them back, so you can't say that the UN is a US puppet either. The UN’s desire to avoid just a few days of conflict (the time to get to Baghdad) was a direct cause of the decade of suffering the Iraqi people have endured. Blame the UN, not the US.
The WTC attack was targeted at civilians. There is absolutely no excuse for that. I can almost understand an attack on a military base, or even the Pentagon (as part of military command and control, it is a legitimate target). But the WTC is way out of bounds, so don't even try to make excuses for it.
Why is it that people like you blame the US for all their problems, and blame the US again if they don't give particular attention to a problem. Did the US have a responsibility to help the Afghans rebuild after the Soviet pullout? No. It would have been nice of them, and in hindsight it might have avoided some problems (although surely some people like Bin Ladin would have resented it as well), but there certainly was no responsibility.
The U.S. is the country the world loves to hate. They are cursed and attacked whatever they do, whether it is minding their own business or trying to help other people.
Is killing innocent Afghans the answer? Of course not. Killing guilty Afghans sounds good however. Unfortunately, they are cowards, like all terrorists, and like to hide behind the innocent. If there is no other way to get to the guilty except through the innocent, well, that's war. Name me a single war where the winner did not shy away from unpleasant decisions like this. If the U.S. or any other combatant, past, future or present, is ordered to restrict casualties to combatants only, they can consider the war lost and might as well pack up and go home.
The key is "what is the target". If the target is a legitimate target (such as a terrorist, or a training camp, or a military asset) and innocent people are nearby, that is collateral damage - unfortunate, but necessary. If the target is purely civilian, with no military or offensive value (such as the WTC) then innocent people killed in such an attack are not collateral damage, but the intended victims of a murderous act. So far, as far as I know, any non-combatants killed in the raids these past few days were hit by weapons targeting legitimate targets. Plus the fact that there were clear warnings given for weeks, unlike the people working in Manhattan who fully expected to come home for dinner on the evening of Sept. 11th.
As to your question as to why the U.S. did not offer food aid before. Where have you been? Afghanistan has not been able to feed its own population for years (not that the Taliban have lifted a finger to do anything about it). The population of Afghanistan has been fed by the international organizations, prima-fascia, but where do you think all that money and food come from - Syria? The U.S. has been sending food there in huge amounts for free for years.
Forming up a marriage of convenience with certain parties has its advantages. The U.S. and G.B. allied themselves with Stalin to beat Hitler, and that was a good thing. We can only hope that such marriages bear good fruit - we are not omniscient.
FACT: Bin Ladin masterminded the Sept. 11th attacks (he basically admitted to it yesterday). FACT: The de facto Taliban Government of Afghanistan is actively supporting him. FACT: The people of Afghanistan are totally cowed by the Taliban, and they need outside help to overthrow them. FACT: The Taliban thinks nothing of the lives of Afghans, they said yesterday that they are willing to lose 2 million lives in resisting. As the number of active Taliban members is much lower than this, this indicates to me that they intend to use their own population as human shields (Who knows, they may have killed a few of the "bombing casualties" themselves). FACT: Just as in the Gulf War, bombing raids are just to soften up, not actually change things on the ground. Ground troops are needed for this. QUESTION: Where will those ground troops come from?
The only thing you should feel when shooting a terrorist: Recoil.
