Bro, indeed we in promise with ALLAH for the safety of holy places. Secondly, when it comes to Saudi Government, IMO, we can play a mediation role between two regimes/Islamic Countries but here it is the matter with Rebels that firstly overthrew a Government in Yemen and now are escalating things in other lands. Previously, Pakistan denied to take part in Yemen Conflict but if the matter escalated to Saudi Land by rebels (kindly note that not other government) then we may see a change in our diplomacy as well as our approach for our brothers that we cannot forget their support for us during crucial times. These are not called a deal at all but a bond between countries that enjoys brotherly relations more than friendship.
However, the same is my opinion and currently does not represent the official stance w.r.t. support in Yemen for Saudi Government though our responsibility for safety of holy places, is well known to all and there is no doubt about that.
