Bush and Obama have, by acting in concert against the American people and the constitution, fundamentally and permanently undermined global trust in any American company. (Secret courts indeed!)
The US internet industry will be lucky to recover, if indeed it is even possible at this point.
No foreign business or government or municipality paying attention will ever trust high-value confidential data to Amazon, Google, Apple, Facebook, or Microsoft ever again.
Remember that all of these companies have substantially more customers outside of the US than they do who are US citizens.
Even if PRISM/MARINA/MAINWAY are provably dismantled (fat chance), we have demonstrated an innate untrustworthiness at the highest levels of government, from both red and blue. Trust is incredibly easy to destroy, and famously difficult to rebuild. We've now got video of them lying under oath - what's to stop them building another in the future and lying about that one, too? We (both US and "foreign entities") would have to be stupid not to expect them to do so, given what we've learned in the last month.
In this case, the regeneration of trust simply won't happen. We'll see tons of national commodity services spring up in dozens of industrialized countries simply because our leaders have destroyed our industry with their reckless, short-sighted, fear-based warmongering.
Indeed, Snowden's disclosures will be the proximate cause of grave and irreparable damage to US interests, industry, and national security. The problem though, is that the root cause of this damage is shitty, warmongering, fear-driven leadership that is willing to shred every last semblance of the enduring values of this country to game the fickle court of public opinion, pretending to pursue security but instead ushering in a totalitarian nightmare that had been previously confined only to fiction.
We passed from the realm of "incompetence" into "malice" territory some time ago— and if you think that's exaggeration, I urge you to review the disgraceful treatment of Bradley Manning at the hands of the US military prior to even being granted a trial.
Sadly, I am vividly reminded of George C Scott's incredible performance as General Turgidson in Kubrick's "Dr. Strangelove", explaining excitedly to those assembled in the Pentagon's War Room why it'd simply be best for the USA to launch a nuclear first strike, immediately killing hundreds of millions of people (including dozens of millions in the US)—to preserve American values. The mind reels at the scale of the irresponsibility of these decisions undertaken in our name and on our behalf. There's a damn good reason why they teach the system of fallible humans and interlocking governmental checks and balances to every ten-year-old child in social studies class.
(A corollary to these conclusions: the corporate rulers of this country, should they wish to continue existing, must dismantle the Nash equilibrium formed by the MSM/GOP/Democrats, lest continued destructive collusion between the only two currently viable parties in the US completely destroy the nation's remaining competitive advantage in the global marketplace.)
