Some corrections. The Taliban are not Arabs, but of the same ethnic stock as other Afganistanis. They are fundamentalist Sunnis muslims. Afganistan was muslim before the Taliban took over, but the previous rulers were more moderate, much like Mubarak in Egypt and the Hasshemite monarchy in Jordan.
Iran is not Arab either, but it is fundamentalist Shiite Muslim, and it does support terrorits, but different terrorists than those supported by the Taliban. The terrorists supported by Iran don't get along with those supported by the Taliban since Sunnis and Shiites don't get along.
Examples of Arab governments that do not harbor terrorists include Jordan, Kuwait, UAE, Egypt (I know that some ordinary Egyptians celebrated after the tragedy, but Mubarak does not support or harbor terrorists), and Saudi Arabia. Arabs are an ethnic group, and not all Arab countries have fundamentalist Islamic regimes.
Nor is a fundamentalist Islamic regime a sufficient condition for the harboring of terrorist. Saudi Arabia has a very fundamentalist regime, but is a US ally. On the other hand, Iraq is staunchly secularist.
So you see, people, things are a bit more complicated than you might imagine.
She is one of the few who hasn't had to change her name several times, so she must not be too bad.
