The Subject Of International Affairs Is Concerned With The Study Of Diplomatic History Of The Leading States Of Europe Uptil World War I. The Focus Is Confined To The Role Of Some Major Powers Like Great Britain, France, Germany, Russia And The Austrohungarian Empire. Situation Changed After World War I When The United States Of America Abandoned Its Policy Of Socalled Splendid Isolationism And Instead Took To The Course Of Cautious And Calculated Involvement In The Affairs Of Europe And Activised Its Role In Affairs Of The Far East With Greater Vigour. The Establishment Of A Communist State In Russia Emerged As A New Factor What Was Denigrated By The Capitalist Powers As The Creation Of The Second World. Situation Further Changed After The World War Ii When A Very Large Number Of Nationstates Came Into Being In The Asian, African And Latinamerican Region Whose Collective Entity Is Now Denigrated By The Capitalist Powers As The Third World. Naturally What Was European Affairs In The Pre 1918 Era Now Became International Affairs In The Real Sense Of The Term.
