I want to know the answer to the following question:
The Imperial War Cabinet was created by which British Prime Minister?
All the background I'm provided with is that "The contributions of Australian and New Zealand troops during the 1915 Gallipoli Campaign against the Ottoman Empire had a great impact on the national consciousness at home, and marked a watershed in the transition of Australia and New Zealand from colonies to nations in their own right.". Is that enough to answer the question?
Answer: yes
