which government spent the smallest percentage on defense?

During the World War II in 1937, the most dominant countries that fought and became powerful are Russia, United States, and Germany.  Because of this reason, I believe that they have the biggest allocation of their budget on military spending.
The least among the three would be Russia since the United States had been busy on providing military assistance and getting involved in wars, while Germany was busy dominating Europe. 

That president would be none other than president warren g harding , return to say of life before wwi

Political forces often influence public opinion.
