I believe what Edward Snowden did was very brave and courageous. I personally think that he should be allowed to come back to the United States without fear of prosecution. However, since the NSA is so powerful this will probably never happen. Therefore, I think he should stay in Russia and have a great life.
Snowden's actions were those of a patriot attempting to protect the people of his country. Unfortunately, the authorities of that country did not agree or recognize Snowden's heroism for what it was. As a result, his life would probably be forfeit if he ever returned to the US. Snowden should move to Russia where it will be safer for him.
