In Sacrifices of Angels, Sisko talks the Prophets into destroying the fleet of Dominion ships coming through the wormhole. if the Dominion fleet had come through, the Allies would probably not have been able to retake DS9. In What We Leave Behind, the Allied fleet seemed to be losing the battle when the Cardassian ships decide to switch sides. And at the end, it certainly seemed like the Allies were going to take very heavy losses attacking Cardassia Prime but Odo successfully convinces the Founder to surrender. These are 3 instances where if events had happened differently, the Allies probably would have lost the war. So, were the Allies "lucky" to win the Dominion War? Now, I know the Allies won because the writers wanted the Federation to come out victorious. But in-universe, could the Allies have won just on sheer military strategy and tactics alone?
