For the Pakistani man on the street, the relationship with Saudi Arabia, the custodian of Islam’s two holy sites, is literally an article of faith. A Pew survey in 2013 found that 95 per cent of Pakistanis had a favourable opinion of the desert kingdom, and Pakistan was the only country in the Islamic world where favourable opinion about Saudi Arabia had increased. In the face of all this, it is nothing less than extraordinary that Pakistan is taking its time to think over the Saudi “request” for air force jets, naval ships and ground troops (for its battle in Yemen), writes Nirupama Subramanian.
