So NSA got nothing to show for it dragnet surveillance. Instead they just start making shit up in propaganda news that they spread with big U.S media companies. The reality is that such attack would never have worked and the people in China knows this already.
China also doesn't need to do this. All they need to do to ruin U.S economic is to stop exporting cheap stuff (among other things) to the U.S. In less then 8 months U.S would be on it's knees in terms of economic performance. Since it is already junk and is not improving thanks to the idiot bible ass-holes who know nothing of economics or facts.
