Um... The 'Internet'* is not 'owned' by any one organization or country. That is sort of the whole point of the internet.
*As the name suggests, it is an INTERconnection of discrete NETworks, each independently owned but cooperating to work together for their common good. (Bunch of socialists!)
The US defence department developed many of the protocols that allow this to happen, on top of a lot of, I believe, British technology, with Australia contributing a good chunk of the technology allowing the wireless bits.
The US is, of course, entitled to do what they like with the pieces they do own, just as the rest of the world is entitled to rout their own pieces around the damage as best as they are able.
