Original post by woIfieWhen you say strategic aim, in some ways you're not far off but they absolutely didn't intend to hit a hospital. But your intuition is in some ways right I suspect, let me explain why.
You have to think about it in context. First, it didn't just come at random. There had been an incredibly intense battle raging in Kunduz for days between the Taliban and government forces. Second, the hospital was right in the centre of the battle. Third, this was happening at night.
The AC-130 gunship received a fire mission, a set of GPS co-ordinates, and they did what they are supposed to do; fly into position and fire on the target. What was happening was that a Pakistani intelligence officer was in the building directing Taliban forces (very murky relationship there), and that there may have been some fire from the building. Likely the National Security Agency was listening in on this Pakistani intelligence officer's phone calls and transmissions, and thought "Let's get this ****er". They used their SIGINT technology to triangulate his position to a GPS co-ordinate and passed it on as a fire mission to the AC-130, without double checking what was actually there. They were probably really excited to nail one of the bastards who sits above pulling the strings of the Taliban, not realising they were about to order the gunship to fire on a hospital. From what I've heard and read, that is one scenario I think is the likely one.
There's no way the Americans would fire on a hospital deliberately like that, not to sound cynical but especially not a hospital with Western volunteer doctors in it. It is just so counterproductive and the ****storm of negative publicity so embarrassing for the President that they would not purposely do something that would lead to their boss (President Obama) coming under that kind of criticism. It definitely was a mistake, it's about finding out how this set of co-ordinates was passed on to the gunship and why.
I don't think de-Baathification was a mistake per se, but disbanding the Iraqi Army immediately was. The sunni generals went to American commanders and said "We can keep our men in line, all you need to do is keep paying them their monthly salaries" (a pittance of $20 USD). A very rigid American official refused. Army commanders on the ground went up the chain and got that decision overturned, but it was already too late; 400,000 sunni army officers and enlisted men left their barracks with their weapons, many ending up in the insurgency.
But it also must be remembered, the Americans did defeat Al-Qaeda in Iraq. In 2007, President Bush took the decision to surge American troops by sending in another 50,000 and put General Petraeus in charge. With these additional troops, they took the fight to the terrorists. They also convinced the Anbari Sunnis to come over their side and fight against Al-Qaeda (the Anbar Sunnis by that time knew just how evil Al-Qaeda was). And the strategy worked; in 2006, around 50,000 Iraqis were killed (that is by whatever side). In 2010, only 5,000 were killed (which is comparable to South Africa's murder rate).
By the time the Americans left in 2010/2011, killings had been reduced by 90% and Al-Qaeda in Iraq had been devastated and pretty much defeated. They were barely hanging on out in the Western desert. But it was the Americans leaving that allowed Nouri Al-Maliki to really start persecuting the Sunnis to please his Shi'a political base. They started rounding up Sunni political leaders, young sunni men were turning up dead everywhere. Shi'a death squads working within the Ministry of Interior and the Ministry of Health (surprisingly) were going crazy killing sunnis, and there were also massacres of Sunni protesters.
At the same time, the Syrian Civil War was taking off and Al-Qaeda in Iraq elements went there to fight, and over time managed to really build themselves up into a big fighting force by concentrating on taking territory (rather than directly fighting the regime) and by focusing on making money and stockpiling arms. So fast forward to 2013/14, by this time the sunnis of Iraq have absolutely had it with the Shia government. And this is how Al-Qaeda in Iraq fighters (now called ISIS) were able to return to Iraq with masses of weapons and recruits, and take over lots of sunni cities.
In that history, I see a lot of blame to be put on sectarianism and corrupt political leaders in Iraq. I can't really blame the Americans for what ended up happening, they actually left Iraq in a (relatively) pretty good state, Iraq had a huge opportunity to take it from there and run with it. Instead, its leaders indulged their sectarianism
