Think of what the Obama decision really says...
The United States, with all it technological skill and business expertise, is incapable of building and operating a long steel tube that won't leak.

This is the same country that put a man on the moon? And we're going to make wind or solar power a major industry? Yeah, right.
Unbelievable!
