Today 19 years ago I was trying to work from home and found it was almost impossible to work as most people were, like me keeping one eye on the TV in sheer disbelief at what was unfolding and I for one hope that we never have to watch similar scenes ever again. I still can't comprehend that any sane person could carry out such a disgusting attack on so many innocent people who were just going about their normal activities. My brother-in-law was actually on his way to work on the train at the time and his office was just round the corner, and we were very concerned about his safety, but luckily he was running late on that day.
Oh I can understand it, but that is not the same thing as condoning it. You only have to consider the history of what America (and let us not forget Britain too) have done to and in the Arab world, with effective impunity, to understand why individuals from nations in that milieux, that have never really been able to resist or fight back conventionally, would opt for that kind of asymmetric warfare. It stands to reason that if you maltreat enough people for long enough that there's going to be some of the maltreated who crack and lash out; in a sense it was inevitable given the history. That, as I say, doesn't justify it, but it does make it understandable.
the conflict between Arabs and Americans goes back a long time and it was not the Americans that started it.
Kidnapping sailors from merchant vessels and holding them for ransom or selling them as slaves is not a friendly act. When trying to negotiate peace, the arab response was:
It was written in their Koran, (that all nations which had not acknowledged the Prophet were sinners, whom it was the right and duty of the faithful to plunder and enslave; and that every mussulman who was slain in this warfare was sure to go to paradise). He said, also, that the man who was the first to board a vessel had one slave over and above his share, and that when they sprang to the deck of an enemy's ship, every sailor held a dagger in each hand and a third in his mouth; which usually struck such terror into the foe that they cried out for quarter at once.[24]

https://en.wikipedia.org/wiki/First_Barbary_Warwhile enslaving Africans is by no means acceptable (see American history), neither is piracy and kidnapping of sailors.
There have been many atrocities committed by various arab groups, especially Black September, who marauded in Jordan and forced King Hussein into action, when they kidnapped 4 US airplanes and blew them up. King Hussein had to show the world that he was still in charge of the country and threw them out.
Anyway. trying to invade Afghanistan was a stupid idea and a huge mistake by George Bush.
Still I cannot condone or understand the senseless murder of others just based on them not being muslims.
