Two more things that occured to me after reading the whole thread:

- Germany (and I guess, at least in Europe, all other countries) have expressed and still express their condolences. Flags are lowered, people go to church and lots more

- Let's please not make any assumptions about who it was until we know for sure and let's not try to get any prejudices. Also, even though that sounds pretty hard for those actually involved, don't do an overkill revenge. That would lower you to the same niveau as the terrorists. As it seems, this attack was not done by a country, but by a group of people. I understand that the responsible persons have to be found and punished, however, this has to be done in an "acceptable" way. Whether there is / might be / has been a country involved backing up this group is a different question and has to be treated differently as well.

- Bin Laden has (according to various news sources) indeed been funded by the USA some time ago
