Answer: -"Kaiser" German word for emperor.
Explanation:
The word "Kaiser" is a title used by the rulers of Germany and Austria. Therefore, the fate of Europe was not in the hands of the Serbs and the Russians. Therefore, the main role, in this case, is played by the Germans primarily and then to a lesser extent by the Austrians.
The Austrians wanted to maintain dominance in Southeastern Europe, mainly the Balkans. That's why they go to war. However, German plans are more global in scope. The Germans wanted primarily to conquer France and Britain to take over their colonies. Therefore, we can say that the war in Europe was decided more by Germany than by Austria.
