OK, see below...
OK, I didn't read the article too closely. My fault.
In that case, the author is having a drug-induced hallucination.
The reason the US (or Israel) can carry out such operations is NOT because of super-advanced technology, or particularly galling temerity, but because their operations are backed by the full might of their military capability. The adversary is powerless to respond even if the operation had not been covert.
In other words, much as the US media brags about the "bravery and skill" during the OBL raid, the fact is that there is very little Pakistan could have done even if the operation had been intercepted. Every US soldier is implicitly backed by the entire US military might and any country that takes him on risks escalating the conflict to involve the full US military machine.
In the case of India, there is no such overpowering disparity with Pakistan. Any Indian misadventures would trigger a response from Pakistan because the conflict escalation is manageable by Pakistan. In other words, before launching any covert operation, the Indian planners must be willing to accept full escalation as the worst case scenario.
