No. Absolutely not. The Antares flight used refurb-Russian engines, and Antares could not be used for manned flight anyways. Even if Antares was flying great, the US would still depend on Russia for rides to the ISS. If the Russians wanted to sabotage something to make sure that the US remained reliant on them, it would be one of the launchers that will be used for manned flights in the near future; Atlas V or Delta IV (CST-100) or Falcon 9 (Dragon 2). Virgin Galactic threatens approximately fuck-all of what the Russians do. Their spacecraft cannot bring people into orbit. In no conceivable way did Space Ship Two make the US any less reliant on the Russians.
