One of the more remarkable documents found in the Osama bin Laden compound included a letter to the Islamic State group of Iraq and Syria cautioning Abu Musab al-Zarqawi over his group's extreme violence.
The insurgency in Fallujah and Tal Afar had alarmed the al-Qaida leadership in Pakistan as to how they would justify such brutality to the wider audience that they sought support from. This is perhaps the most significant question as one tries to analyze Islamic State strategy in Asia. Over the last month, Islamic State literature has been found in mosques and schools in the northwest of Pakistan and the group's flags have been found in India, Indonesia and Uzbekistan.
