War is hell, things happen.The US went into Afganistan because the Taliban were harboring terrorists, that is the truth, no spin.Now, the war was mismanaged under Bush since he was sidetracked with Iraq.The focus is on Aghanistan now and hopefully it will work out.The US was not the aggressor, terrorists had a home in Afghanistan and the Taliban was aiding Bin Laden and his bunch, so they were accessories to 9/11 in a sense, thus they were the aggressors.People who argue the US was the aggressor are usually the great thinkers
who say Japan was not the aggressor in the Pacific, that America provoked Japan.
No matter what there will always be a segment of Afghanistan that is unhappy with the US being there and the change due to their ignorance and backwards way of thinking heavily influenced by the great
pestilence nown as Islam.However, the US and Allies in the country have done a lot of good by building schools, hospitals etc and setting up a government to build a better nation where women and girls can learn to read and have choices.That government is much perfect, but no government is.
Bottom line, it is sad that some civs died but it was an accident and these things happen in war but things are getting better there and great care is taken to prevent civ casualties but it happened and will most likely happen again at some point, part of war and building a decent society in Afghanistan.
