There's a huge difference between what Google Earth can do and what spy satellites do. Spy satellites provide real-time views of the earth, allowing the military or NSA to do things like to track troop movements. Google Earth is not real-time. I'm not sure how often they update it; as recently as about 6 months ago, when I looked up my mother's address I saw the state of the new development from about 3 years ago (they've since brought it up to date and I can now see her house).
