Commentators predictably reacted to the news of the signing of a mutual defence pact between Saudi Arabia, Turkey and Pakistan on August 7 by reaching for the label “Islamic Nato”. The Mecca Joint Defence Agreement stipulates that an armed attack on any one of them would be treated as an attack on all.
