As I said, when Pakistan falls apart, US would be far more worried about their own butts. US has men and material locked up in Afghanistan that will become the first target in the on going war. And geographical isolation didn't stop 9/11 from happening.
The Chinooks and Apaches are not stealth jets. They flew unchallenged deep inside Pakistani airspace over densely populated Abbotabad which also has their main military base, only a few miles away from capital Islamabad and only a few mile away from Indian border. You really think you caught Pakistan by surprise with American military capability?
Bin Laden outlived his usefulness to Pakistanis. Regardless of what military capability you may have, if Pakistani air defense had decided to engage, those Apaches and Chinooks would have dropped down like flies.
Yes controlling Afghanistan until the Taliban was completely destroyed and installing a friendly/democratic government was the US objective in Afghanistan. Until those objectives were later on deemed unachievable and thus today its watered down to simply cutting and running. Obama govt invented a fictitious “moderate Taliban” with whom they can now come to a “settlement”. Fact is US lost in Afghanistan.
Even when Taliban was at its peak the couldn't do much in Kashmir. Apaches, Chinooks and special forces raid make for interesting cover stories. They don't necessarily win wars.
Claims by Pakistan's Islamists that they do not regard India as an enemy ought to be taken with much caution. The ISI guided attack on Mumbai and Pakistan's growing nuclear arsenal pointed at India suggest that Pakistan thinks of India with something other than affection.
Apparently, newer US technologies can spoof targeted radars to the point of disguising intruders as if they are innocuous. As you hint, the US may also have had the benefit of bribery or covert official assistance in the Bin Laden raid.
