Why make such extensive theories when the entire situation can be easily explained by the fact that america doesn’t want India to destroy pakistan, since pakistan is a useful tool to counterbalance India. The urgency likely came from the realization that things were deteriorating quickly and a ground incursion by India was on the table. As for why Modi backed down, it was probably because they threatened heavy economic sanctions. They might have also offered a few incentives both economic and political in return for us if we decide to pussyfoot. If what you said were true, I don’t think pakis would have dared to break the ceasefire and attack us with drones and terrorists just after 2 hours of it being inked.
Still, I can’t wrap my head around the fact that, right after we declared any terrorist attack would be considered an act of war, we immediately buried all information about the Pakistani attack and acted as if nothing had happened.
