“I indicated in a speech at the National Defense University last May that we needed a more robust public discussion about the balance between security and liberty. Of course, what I did not know at the time is that within weeks of my speech, an avalanche of unauthorized disclosures would spark controversies at home and abroad that have continued to this day. And given the fact of an open investigation, I’m not going to dwell on Mr. Snowden’s actions or his motivations; I will say that our nation’s defense depends in part on the fidelity of those entrusted with our nation’s secrets. If any individual who objects to government policy can take it into their own hands to publicly disclose classified information, then we will not be able to keep our people safe, or conduct foreign policy. Moreover, the sensational way in which these disclosures have come out has often shed more heat than light, while revealing methods to our adversaries that could impact our operations in ways that we may not fully understand for years to come.”

Context: I saw the King on Monday, 16th November, and I began by giving him my view of a possible marriage. I told him that I did not think that a particular marriage was one that would receive the approbation of the country. That marriage would have involved the lady becoming Queen. I did tell His Majesty once that I might be a remnant of the old Victorians, but that my worst enemy would not say of me that I did not know what the reaction of the English people would be to any particular course of action, and I told him that so far as they went I was certain that that would be impracticable.
