Thanks for posting that, I hadn't seen some of those pictures before.
It may have changed the path of the war had it gone into production, but perhaps not the outcome. It's most radical feature was the mounting of the engines inboard with the exhausts exiting above the wing which ensured it remained virtually invisible on radar. Without those innovative German designers (Horten Brothers included) it might have taken Northrop well over the 40-odd years it took to eventually perfect the prohibitively expensive B2. That would have undoubtedly changed the path and casualty rate of the Gulf wars.
