I don't think that would be stable. No war means losing the ability to fight which means eventually it'll be easy enough for just one small group to attack somebody much bigger but weaker.
If war is solved by all attacked countries surrendering immediately so one aggressor rules the world, I'm sure factions would emerge within it who are competing for power again.
Maybe a solution could come from some defensive technology permanently outperforming offensive technology? I think people would still find a way and the wars might be or begin by psychologically changing people's allegiances.
