I want to know the answer to the following question:
Who wrote, "The test of a great power is the test of strength for war."?
All the background I'm provided with is that "Early writings on the subject tended to judge states by the realist criterion, as expressed by the historian A. J. P. Taylor when he noted that "The test of a great power is the test of strength for war."". Is that enough to answer the question?
Answer: yes
