One German tech industry figure I spoke with felt it would be difficult, if not impossible, for Europeans to migrate completely away from U.S. services. He likened America’s hegemony on the Internet to the control Gulf States wield over oil resources. 

“What you have with oil in the Middle East, you have in the U.S. with information,” said Malte Pollmann of Utimaco Safeware AG. “The U.S. is in a unique position of geopolitical strength in the information age—and there’s no other country like this.”

Unlike oil, information is not a finite resource.

You just uncovered the secret to a NSA proof cloud.  Seed the network to full utilization 100% of the time with the exception of certificate based authenticated clients.  As soon as you receive any information, encrypted and send it out across the fiber.  When you get it back again, do the same thing.  There's a lot of storage--even though you are only storing it for millisceconds at a time--in networking and it's hardly ever fully used. 

Here's one example detailing a method. I've seen lots of others.

On the other side, all security is only as strong as it's weakest link.  The only fully secure computing system is one that nobody every uses.
