Really good point. Electronic jamming is where the American's are leaps and bounds better than the rest of the world. Due to the nature of the tech, it is also easier to hide and be secretive about. No nation in the modern world has been able to withstand it so far.
While we may see a massive gap in the capabilities of Pakistan and Iraq & Libya; from the top...where the Americans are looking from, it all looks the same...I know that sounds crude, but the Americans will only find Pakistan a worthy adversary, relative to other third world countries...not in the grand scheme of things. It may take them a few of weeks extra to gain air superiority, but that's hardly the kind of odds you want to play against.
Equally, I have yet to understand what will be gained if we were to shoot down a NATO aircraft...aside from a further deterioration of relations that may lead to a greater conflict Pakistan can't win. Closing off border to NATO supplies is Pakistan's greatest trump card, any military action against a force so powerful is bound to blow up in our face.
If its all for the sake of protecting our dignity...a more fruitful endeavor maybe, to change our pathetic leadership that has allowed us to end up in this situation.
