I want to know the answer to the following question:
Who were  the chief arbiters of the new world order?
All the background I'm provided with is that "During the decision-making of the Treaty of Versailles, Italy pulled out of the conference because a part of its demands were not met and temporarily left the other three countries as the sole major architects of that treaty, referred to as the "Big Three".". Is that enough to answer the question?
Answer: no
