How did the specific ideological differences between the U.S. and the U.S.S.R. lead to the creation (e.g., Mackinder, Roosevelt, and Haushofer) and management (e.g., Truman, Kennan, Zhdanov, and Brezhnev) of the cold war; and following the end of the Cold War (e.g., Fukuyama, Huntington, and Said), what factors were in place ensuring the U.S. as the sole global superpower, and what are the downfalls of such a responsibility (e.g., Barnett, Ignatieff, Lieven, Welsh)? Your answer must make reference through the identification and explanation of the specific ideologies the U.S. and the U.S.S.R. had during this time, and must make reference to each author listed. Be sure to add appropriate citations for quoted ideas, corresponding SAWP Maps (reference and explain their significance) and to watch your spelling and grammar. Your answer can be a maximum of fifty lines and one hundred characters per line so be concise and do not ramble on.
