Snowden was someone with access who acted on what he thought was in the best interest of Americans. Whether it was or wasn't is debatable. But to assume foreign spies exist in the NSA, and would risk treason for foreign interest because NSA screening missed Snowden, is a big leap in logic. Of course no one can say foreign spies inside the NSA or access to their top secret files is impossible, I'm simply suggesting it's safer to assume this is not likely, and comparing the NSA to civilian corporations in this regard is unreasonable.
