The short answer is without a doubt yes. The major powers of Europe were Britain, Germany, and France, with A-H, the Ottomans, Russia, and Italy at most second rate powers. In 1911, colonial rebelions were subsiding, and western ideas were in vogue, even in the states outside the reach of the European empires and ex-colonies. At that point, China is a nonentity, and the United States is only still emerging as a power on the world stage.
By 1979, there are really only three powers of consequence: United States, Soviet Union, and People's Republic of China. Additionally, the exent of colonial empires has not just receded substantially, but nations throughout the world are moving away from westernization, and toward revolution of one sort or another.
