Clearly that is not the case and it's about time that things like this come out. Maybe nothing will come of it but either way I'm not really on the side that believes we're any more endangered with this information coming out. That's just what the gov't is saying to make us look at him as a traitor.
I don't know about endangered, but we are now having to field all kinds of demands from our allies, wanting to know what was bugged, assurances that they won't be bugged in the future, reputation damage, etc.
We have to deal with the hypocrisy issue as well. It would appear that we've been doing all of those things that we've been accusing China of doing. We've lost all credibility here.
Also, American Internet companies are having to deal with a backlash of the government's actions on information routed through American companies like Apple, Microsoft, Google and Facebook. That in itself is an economic harm. Some companies / governments will now make an effort to not route their data through US-offered services in order to avoid the US government's signals intelligence efforts.
IMO, Snowden is right by showing that US government has no bounds and they will exploit anyone and everyone. I don't want to personally attack you but I can't help seeing utter amount of selfishness in your words. You want to put the rights and privacy of the entire world at stake for your interests. I'm sure this will come and bite in your own ass one day. If you deem espionage to be a common practice, then why not see Snowden's case as just another "common" espionage act?
