Why is Osama Bin Laden dead ?
Maybe it`s because his number two man Ayman al-Zawahiri has just sworn allegiance to Mullah Omar. Why do that if your boy is still alive and kicking:
Al-Zawahiri pledged allegiance to Mullah Omar and called on all his followers to reject animosity and differences and come together under Mullah Omar's banner.
Mullah Omar is the elusive, shadowy Taliban leader who slipped away in the early days of the war in Afghanistan. The Taliban held Afghanistan with an ultra-conservative government and sheltered al Qaeda.
