I don't expect you to agree, you are after all one of the biggest fanboys i've met on the net. You must be a car salesman's dream. 'The manufacturer says its awesome so it has to be true since they and noone else should know'.
Building fighters is not so much about building the best plane to the lowest cost. There are a ton of 'politics' involved, The different branches have their fights about being the most important one, LM wants to get as much money as possible and so on. Noone will ever say 'We have spend 20 years and a trillion dollar on a plane that turns out to be not so spectacular as we thought'..
The public should trust the professional soldiers to buy the equipment they need, and believe them when they say they're happy with it. If the public can't even trust their own military on something as basic as that then the country has a lot bigger problems that a potentially dud jet fighter...
Usually noone cares until the soldiers are killed due to poor equipment, it has happened multiple times before.
