The reverse is also true. However, we have an obligation to spy on Israel as they spy on us because our interests do not always overlaop. Moreover, it is important for the Israelis to know we spy on them; and vv. That avoids surprises and is protective that Israel does not do something not in our best interests and VV. Often enough they do something not in their own best interests, so how can they protect us; and vv. Needless to say the US does not always serve its own best interests. Who can make that decision? The bottom line of course is that all this noise about American spying on allies is total BS. They know we do. Why is this even an issue? This guy Snowden is a criminal nevertheless. It was not his role to make the point. Israel spies are in US jails. Why not American spies?
