Why Allied powers won WW1-
More than anything it was the British naval blockade which kept the Central Powers from getting sufficient amounts of ammunition, food, medical supplies, and so on to continue the war past 1916-1917. If it hadn't been for this it's probable that either the Germans would have had a breakthrough. The reason why the Allies won was because they managed to keep all their supplies, such as food and drink and ammunition. They also managed to take out all of the opposition when they were trying to get food and drink and also when they had problems with the shipping. The Allies won over all to do with the fact that the opposition were not prepared. towards the end of the war the tank was invented. the long lasting war really hurt the german economy which made them pull out of the war.
