Uh, it's been happening to the US for decades, with nobody seriously talking about war. The most recent "famous" example that hit the news was Chinese cyberattacks into Google (the "Aurora" attacks), which didn't elict a drumbeat for war. In fact right before Snowden Chinese industrial espionage was one of the topics that President Obama discussed in a summit with the Chinese Premier (which, again, was reported in the media).
