USA does not need "non state actors" to wage war against any country, least of all Pakistan. Their armed forces are more than capable of decimating any country. Such tactics like "non state jokers" are for states that don't stand a chance in conventional war. And such tactics don't work against a determined nation anyway. (As many non state jokers have realized in Kashmir.)
If USA wanted to wage war on Pak, it would send in three carrier strike groups and a few marine expeditionary units. The resulting war will last only a few days at most.
Get rid of this delusion that all this is happening because of CIA/Mossad/RAW. Until you accept the fact that these are YOUR citizens waging war against YOUR country, you will not be able to tackle them properly.
