I'd like to add,

The Gulf States are already under Sharia, and have been since their founding almost a century ago. The Taliban copied Saudi Arabia, even using the exact same names for bureaucracies. [2] Relations with them were excellent before 9/11.

But, as Iraq showed, there's no need to understand elementary facts about their culture before you invade and engage in a massive social engineering project, or engage in an global, eternal, "war on terror".
