US National Intelligence Director James Clapper said that the activities of former employee of US special services Edward Snowden caused great damage to US intelligence.
In an interview with The Washington Post, Clapper explained that "we've been very conservative in the damage assessment. Overall, there's a lot," Clapper said. According to the official, Snowden's disclosures made terrorist groups "very security-conscious" and gave an incentive to the encryption of data.
The head of the US National Intelligence also stressed out that Snowden's revelations may not have come to an end. "The assumption is that there are a lot more documents out there in escrow [to be revealed] at a time of his choosing," he said.
