Well, this is fun, I get to agree and disagree with both of you! First of all, parent makes the right point (that I irresponsibly glossed over) that aside from the US and Al Qaeda, there were a bunch of Iraqis responsible for the majority of the deaths in Iraq. I wouldn't be all that surprised if the number dead is over 300,000, and that number (whatever it really is) does matter to me. The US is largely responsible in the sense that we opened up the can of worms, but the Iraqi factions and Al Qaeda are the primary killers, particularly in terms of innocent civilians. I do not think the US administrations have done enough to avoid civilian casualties in many instances, particularly when it comes to bombings based on bad intel, and particularly the Bush administration. Maybe it's just the coverage of bombings of things like weddings has decreased, but I've seen many fewer instances of this sort of thing in the news over the past year or so. That all being said, there is a difference between what we do and what they do in that we (usually) make a concerted effort to avoid civilian casualties, whereas the others not only don't mind killing civilians but often target them outright.
So both of you, please put away your extreme and overly simplistic perspectives. The US carries responsibility in that we made choices and need to recognize the consequences of those choices. However to cast all blame on the US and fail to distinguish between motivations is just as childish. Obama is no leftist. Your statement saying he is tells me a lot about you, tiqui. Obama is a centrist with liberal roots. Moreover his actions, while in my opinion unconstitutional, are far less reaching than Bush's were in terms of starting an endless war against "terrorism", promoting torture as policy, and denying rights to citizens and prisoners of war alike (yeah, the Geneva Conventions are still relevant until a person has been processed to ensure they were in fact enemy combatants, something Bush failed to consider for a substantial amount of time as many innocents got stuck in Guantanamo for years). So let's can the false equivalencies but recognize the US's role and responsibility with regards to civilian deaths and mistreatment. The problem hasn't been "a few bad apples", the problems come from the top in the way we put our soldiers into war, and more specifically into a situation of having overcrowding in prisons and insufficient training and supervision. There were a few bad apples, but most of the poor treatment and bad action by US military has been due to military and civilians policies and implementation.
