We are making a mountain out of a molehill.
Firstly, this is just a representative hand made sketch showing the general route taken which was from the East of Abbottabad, but originating from Jalalabad. This does not in any way mean that they flew over Indian territory, just because of a fancy 'broad brush' arrow depicting the route taken which unintentionally covers a part of Indian territory!
Secondly, it would have been impossible for the choppers to cover such vast distances without refueling midway.
Thirdly, either Pakistani air defences in the East were caught napping which is unlikely or they were all jammed during the flight of the choppers which needless to say is impossible, considering that US planes capable of jamming were flying hundreds of miles away over Afghanistan or over the Arabian Sea.
Fourthly, crossing the LOC would have been an exceedingly dangerous undertaking, and one which certainly would have required providing prior notice to the Indian government. Likewise, crossing back over the LOC into Pakistan would have been a dangerous undertaking, as that is the direction in which Pakistan’s air defenses are largely oriented, unless Pakistan's permission was taken too!
Or, keeping the above in view, were both India and Pakistan privy to the operation, and taken into confidence by the Americans? Now, that's an interesting point! Who knows? In international diplomacy there is undoubtedly a lot of behind-the-scenes and cloak and dagger stuff that we ordinary mortals will never be privy to.
But as I mentioned above, this most likely is nothing but a crude representation of a route taken by the Seals that goes unwittingly over Indian territory. Such arrows that are drawn on maps with a swish of the broad graphic pens only indicate the general routes to be followed.
So this one seems to be just a conspiracy, but of galactic proportions! Unless all three - US, Pakistan, and India were in it together (if that map is a true representation of the actual route taken).
