I don't think so, Russia/China getting what they want (the degredation of America) is more likely to avoid war. However it is one of the strongest signs yet that America won't be the main superpower when Trump "leaves office".
At best, should a responsible/intelligent leader return one day, there will be a protracted period of cold war like tensions and instability, as there has been before.
However recent events do seem to indicate that America's decline is rapidly accelerating.
