I expect that the theorists are champing at the bit with this one!
What will any self respecting theory include?
NASAs lack of credible power units for ISS support and maintenance
USs lack of power to deliver warfare ordinance
Virgins use of Russian power units that it may be able to "give"to the US and NASA.
Prospect of the US relying on Russian technology to fight its war against, er, Russia
Too much money and too big outcomes to allow anything normal to happen without someone lining their trousers.
