Regardless of whether you think that Edward Snowden is a traitor or a hero, the facts disclosed so far show that there were many people with top security clearances who had access to NSA data; that the background check on Snowden was poorly done; and, that the rule regarding the use of flash drives at the allegedly secure facility where he worked was poorly enforced.
It seems likely that the intelligence operatives of China and Russia detected these weaknesses and placed their own respective agents inside the NSA to gather data.
Why wouldn’t they? It was an easy thing to accomplish. I would be greatly surprised if any of our enemies learned anything from Snowden’s release of data that they did not already know.
