To defend myself against the downvoters who may not have made the same connections: Aaron Barr talks to Defence Intelligence Agency and DoD about StuxNet in 2010, they had a copy given to them in 2009 that they claim was a US produced binary. Keep in mind stuxnet was 'discovered' in 2010.

First reference to Stuxnet being U.S. government produced?

They had a binary they believed was US produced. It was Stuxnet. It was 2009.
