Us can never be assumed, it has always provided the world with panic attacks as wellas the territorial. U.s can never afford to loose the puppetic state,unfortunately its ours, yet never allow to let pakistan stand as its never going to be in its interest. Us always needs a reason to deploy troops on other countries especially who can threaten its aim. Pakistan,s struggle in itself is now making the youth aware of the rights and wrongs, this might be the reason to increase the worry for u.s. Such worries strenghten the hawks[us] grip towards its prey[pakistan].
So, the attacks might provoke pakistan and press the red button that u.s wants to be pressed so it cut encounter its will with a clean collar defending that they never wanted to fight against pak but when it comes to their soveriegnty they cant step back..
" one sure thing is that u.s never explains its personal benefits or interests, all us wars are namely for the cause of protection which gives them an option to increase influence and yet live clean handed!
