The original document seems near pointless to me and this article is just trying to grab attention with a catchy/controversial title...typical politics and media...
Title of article- US: if you hack us, we may use military action
Reality- US: .."insert anything", we may use military action ...gotta love this country..
Another way to put it is: if we launch an attack on ourselves we blame a country such as Pakistan or Iran and go bomb them. Anything is possible to advance the Anglo-American world empire.
