I can't see the justification in arguing this point. It makes no difference what the circumstances are, 40 people where killed. Is this not a tragedy in itself? All you are really arguing is where to allocate the blame.
The fact that the US troops are there illigally in the first place concerns me more than anything but more than this, all these terrible things that are happening, 40 killed at 'wedding' party, Daniel Pearl and Nick Berg execusions, Iraqi prisoners pissed on and humiliated etc... all these things are done in OUR name. We elected our leaders into power so when they fail to find nonviolent solutions to the worlds problems it is our perogative to change the leaders.
It is everyones responsibility to respect and champion human life. I understand that the right-wings blood is boiling over with the events of the past 4 years and all the attrocities that are carried out against you, however, you need to see the bigger picture. Agression only leads to agression, it is an ever decreasing circle with only one logical conclusion and nobody wants that.
Please, please, everybody just think about what is happening. Forget your alligence. We are all a part of the same species and only our voices can stop what is happening.
