Which of these groups would have supported the Five-Power Naval Treaty of 1922?

taxpayers of all the nations involved

shipbuilders of all the nations involved

naval officers of Britain and the United States

the nations on the losing side in the Great War

Considering that the treaty imposed military quotas regarding the size of the fleet and that it forced the US to reduce it's army size, the correct answer is probably taxpayers of all the nations involved. That would mean that the common people have to pay fewer taxes because army and the navy are usually built out of tax payers' money.
