In 2011, the Pentagon released its first formal cyber strategy, which called computer hacking from other nations an "act of war," according to the Wall Street Journal. In late June of this year, WSJ reported that Edward Snowden, the NSA whistleblower, released information alleging the U.S. government was hacking Chinese targets "that include the nation's mobile-phone companies and one of the country's most prestigious universities." Now that EU offices have been hacked by the U.S. government as well, one must wonder if that was an "act of war" on the part of the United States. So my question is, how many nations is the US at war with? From quotes made by US government itself and the revelations made by Snowden, it is clear we are at war with EU and China at the very least. No wait. I must rephrase my question. IS there any nation on Earth with which the US is not at war with?
