Al Qeida (The Base) was created by Osama Bin Laden in 1988 made up of ex-Mujahedeen fighters soon after the Russian/Afghan war.
True, but Bosnia shaped and grew al Qaeda into a real force -- and we helped them.
You have to understand the Islamic world to get that they have more respect for their enemies than they do for faithless "friends". To them, we betrayed "our own" (Bosnian Serbs, ie Christians) and that is beneath contempt -- and we supposedly "befriended them" while blowing the civil war out of proportion and then pretended to sit by while Bosnian Muslims died --that is humiliating to them.
You can't think about radical Islam in terms of adult discourse -- instead think of them in terms of narcissistic teenagers with an over sized sense of male pride. Because their women are nothing but "breeding stock", Muslim men never grow up. They remain puffed up little peacocks for life and every loss is "a humiliation to be avenged".
