I don't get it. I thought that Muslims were only supposed to kill "infidels" (non Muslims).
Islam was spread with the sword, "Convert or Die".
Read this, from OBL's "spiritual mentor" (source below):
As a cultural struggle, the world-wide Jihad is waged on three fronts. The most immediate front is within Muslim countries, where the goals is to reinstate the rule of Shari’a law.
The second front is in countries with Muslim minorities, situated on “fault lines” with other cultures, such as the Balkans, the Caucasus, Kashmir, etc.
And the last front is the international cultural struggle, in which Islam takes on Western— particularly American—civilization, perceived by the fundamentalists as the source of all evil, and the primary threat to Islam.

She looked Western. Since, in reality, the Ba'ath Party, the covert anti Western forces in Iraq (I will *no longer* call them insurgents, that's too dignifying), the mullahs in Iran and other Islamist forces are, essentially, part of a Pan Arabic, Pan Islamist movement, anyone who does not overtly "fit in" with their rabble is fair game. World War is inescapable.
