Actually, most of this stuff, the basis for it anyway, goes back to Eisenhower.
During the cold war the NSA was focused on the Soviet Union, which was an actual real threat to our national security. There is little evidence that the NSA was engaged in domestic spying during that time. Today the NSA, and all this surveillance, is focused on stopping some hermits in Afghanistan from talking to a few guys with a pressure cooker full of gunpowder. Meanwhile, our diplomatic relations with China and Russia have deteriorated, and we have very little idea what is going on in Iran or North Korea. Remember last month, when the Chinese Red Army was identified as actively behind cyber-spying? It was some gumshoes working for a private company that tracked it to a specific building in Shanghai. Meanwhile, the NSA, with their 30 billion dollar budget, was busy reading your email and monitoring grandma's phone calls.
These NSA programs are worse than a crime. They are a mistake.
