The info has compelled British intelligence agency MI6 to withdraw some of its agents from active operations and other Western intelligence agencies are now actively involved in rescue operations.
In a July 2013 email to a former U.S. Senator, Snowden stated that, “No intelligence service—not even our own—has the capacity to compromise the secrets I continue to protect. While it has not been reported in the media, one of my specializations was to teach our people at DIA how to keep such information from being compromised even in the highest threat counter-intelligence environments (i.e. China).”
Many in the intelligence agencies at the time greeted this claim with scepticism. Now, one senior British official said Snowden had “blood on his hands,” but another said there’s yet no evidence anyone was harmed. Snowden eventually fled to Russia via Hong Kong after downloading some 1.7 million documents from U.S. government computers and leaking them to journalists out of a desire to protect “privacy and basic liberties.”
The revelations of mass spying outraged populations and governments around the world, at least temporarily damaged relations, and eventually led to changes in the mass surveillance policies of the NSA and British GCHQ. Read more at BBC News.
