Surfduke, now that the Centrifuge Accommodations Module is not going to be launched, real science is taking a back seat to long duration missions. ISS is baciscally a dead duck without this module. NASA is continuing building the ISS because it has signed agrements with the international partners to finish it. I agree that space should be 'weapons free'. But I don't think that will ever happen, even todays ICBM'S launch into space then come back to earth.
