It could be a precautionary meeting, like I said maybe Pakistan will send its AF for defensive role, to shoot down drones and BM's, now in this day and age, pics and videos will come out if PAF start operation in KSA, so in that the Shia's of Pakistan should not see such operation as Pakistan taking Part in any offensive or bombing campaign against Iran, no matter how many ups and downs we have with Iran it will be very low chance that PA will directly attack Iran or take Part side by side with America/Israel or Gulfie's, remember we said no to send our troops in Yemen, and we got threaten and even paid a dearly price for it.
