This is the case in Lebanon with Hezbollah, in Palestine with Hamas, in Iraq with Moqtada al-Sadr’s Mahdi Army and scores of other groups, with the Taliban and tribal warlords in Afghanistan, and with breakaway movements in Pakistan that have been emboldened by Pervez Musharaf’s resignation. The looming end of President Hosni Mubarak’s long rule in Egypt might lead to the emergence of a formidable bid by the Muslim Brotherhood for power in Cairo, possibly forcing Mubarak’s successor either to reach a modus vivendi or to wage a fight to the death.
