Did these events or others reflect a "failure" of contemporary Islam and spur a re-thinking of the proper way to practice it? Also related, what are the philosophical and political roots of Salafism and Wahhabism?
Recommended reading related to this topic is greatly appreciated! (If you bring up Reza Aslan I'll be very disappointed)
Can you point to an example of Islam's turn to Qur'anic literalism? I'm genuinely curious what you mean.
