Hostility? Not possible. Why? Because we are holding a banner of "COOPERATION with US on WOT" Considering them hostile means hindering their efforts in catching Osama (Near to Americans)
2)PAF could have escorted them out of Pakistani airspace (considering cooperation)
So that Osama can escape? This is what Americans will think so infact they will send their own jets to escort our planes out of the area hence removing us as an "obstacle" in catching Osama
3)Pakistani Army could have secured perimeter for Americans (considering cooperation)
It will make the whole world sure that YES OSAMA was living under the nose of ISI and Pakistan Army from the past 6 years and we never handed it over to America.
4)Pakistani Army's 3000 soldiers could have captured/arrested Americans (considering hostility)
American's raped our whole country and judiciary system for the sake of ONE MAN [Raymond Davis], Arresting some bunch of Marines will help us with what?
Just take a deep breath and think rationally. IF Pakistan knew it had to do something, it had to react with hostility or extend cooperation. Why would Pakistani Army and Airforce do NOTHING IF they knew? Or if they knew, why didn't the news got out to OBL? If no one knew about OBL, HOW COULD PAKISTANI ARMY AND AIRFORCE LET AMERICAN FORCES CARRY OUT A SURGICAL ATTACK? Did it went through their mind that anyone could have been there? ANYONE
Lets face the facts. We did not knew about the operation (as also confirmed by US and Pakistani statements). Americans jammed our security apparatus and easily did what they came to do. At the moment, there is not a single piece of news of evidence to support your claim. We as a nation love conspiracy theories but lets face the truth for once. Maybe this would serve as a wake up call and we can improve our defences?
And yeah, I don't agree with you claim regarding 'balls'. Maybe you dont know but our border forces have previously fired at and actively engaged American forces on Afghan border a couple of times when they crossed our borders. This time, we just didnt knew and Americans were serious
Again, detecting those choppers was NO BIG DEAL. Pakistan has one of the most well equipped forces in Asia.
And firing on American forces once in a blue moon means nothing. More then 900 drone strikes have been made inside Pakistan, how many did we tried to stop?
NONE!
Why? Not because we are unable to shoot them but because we are not ALLOWED to shoot them. We have been downing Indian drones in 2002 and 2005. And they were much smaller drones then that of America's thus means Indian drones were harder to detect but still we shot them down with a single F-16 in the air back in 2002.
The problem is,
You shoot down a drone once, next time it wont come alone, Some couple of Hornets will definitely be escorting it!
