Interesting. Sure you had Turkish political support but that is not evidence of military support. You didn't mention how Erdogan, being the belly-dancer that he is, called for restraints and even requested investigations on attacks carried out towards Indian civilians. And Turkish authorities have denied being involved in SIndoor, while others say they were. Mind sharing some evidence of their military support?
Why I made that remark is because the Mecca Pact can create a multitude of activation disputes that can leave allies isolated. Its 'defensive doctrine' will leave political/legal ramifications on things like who started the war? Who is the victim? Were Saudi-Arabia and Turkey consulted prior to the attack? Also, both Saudi-Arabia and Turkey can determine what kind of assistance is appropriate so at best you may get intelligence (Not from Saudi of course), diplomatic and logistics support.
The reality is Saudi-Arabia will avoid a confrontation with India and Greece because of their economic ties and relations with both countries. And Turkey will be pressured by the States and NATO to do the same, although they might provide some concrete assistance as opposed to symbolic gestures like the Saudis.
If Turkey and Greece get it on, will Pakistan genuinely step in? Be realistic here because I can assure you that NATO and uncle SAM will be knocking at your door and tell you to step down.
Be upright with me mate and tell me it's directed at Iran. I have more respect with honest people than those that skirt around facts.
