Answer:
Serbia
Explanation:
Now before explaining this is kind of an opinionated question and answers could vary from person to person. The reason I believe Serbia is most responsible for the Great War is due to the assasination of Archduke Franz Ferdinand by Gavrilo Princip a Serbian nationalist with ties to the secretive military group known as the Black Hand. It is agreed by most that the beginning of WW1 or The Great War is not only due to this assasination but also due to the alliances being formed pre-war but despite this the actions of Mr. Princip kickstarted one of the bloodiest wars in history that will never be forgotten.
After world war 1 the United States wanted to isolate themselves from things like that because of how bad the war was. They went as far as to not join the league of nations that their President made himself with other presidents. After the Korean War, they decided to not isolate themselves and meddle as much as possible to prevent the spread of communism because it would strengthen the Soviet Union who was the main enemy.
