So will KSA going get it hands on Gwadar for the paid $1.5 Billion as Pak Military might not be joining the Arab Allies at all.
As this would be more helpful for Pakistan to get the Gwadar port being started on.
Also, Pakistan is keen in making better relationship with IRAN in near future too. So, it would be better give KSA back their money of $1.5 Billion in terms of Gwadar. As for rest of Pakistan, Karachi along with new port building like Thatta and Badin would be enough. Our Coast Guards and Navy would be fulfilling the security duties there in.
