Well , i think a better way to start an argument would be by saying the following :-
" As Osama was found in Pakistan , and American forces were operating in Pakistani ground. The Pakistan politicians and public is saying this is against the sovereignty of the nation, therefore the politicians are being pressurized into stop helping against the war of terror "
I being a Pakistani can almost assure you that both nations need each other more than ever, this can be a turning point in their relationship making them stonger allies then before if Pakistani intelligence and army comes out in the open and lets the world know that " did they know that osama was hiding in abbotabad ". But if they do not come out in the open then this can lead to a lot of mistrust between the two nations.
Off-Topic : I still believe that unless USA proves Osama's death they can't ask questions about whether he was in Pakistan , or is this just another tactic CIA has deployed in order to let US troops to start operating in Pakistan like they did in Afghanistan.
Until Osama's death has not been proved properly we can't say that wether Pakistan will break the treaty or not :)
