If Pakistan were as outraged as some posters think it is, or should be, its government would be doing a lot more than just complaining, which I believe is chiefly for home consumption.

It would be going to the UN, recalling its ambassador, cancelling trade agreements, breaking off diplomatic relations, etc., etc. That's what you do when a nation commits an "act of war" against you, assuming you don't have the desire or wherewithal to strike back
with weapons.

Let's see how much of that happens.
