Compare and contrast the early 20th and the early 21st centuries?

As pohnpei357 described how America wasn't even a world power back then as it is now goes to show what time will do to to nations and empires who are willing to stay and become stronger. Such as how Russia (at the time they were the Union of Soviet Socialist Republics or the U.S.S.R) became so predominately strong because of a need to industrialize.
