<human>:  Why did the Arab revolt of 1917 fail?
<bot>: The revolt failed because the British were able to repress it. The British had a huge advantage in terms of military might, which allowed them to defeat the revolt. The British were able to use the railways to transport troops to the revolt’s location, and they also had a large number of aircraft and armored vehicles. The British also had a significant amount of money and weapons, which allowed them to buy off the rebels.
