I want to know the answer to the following question:
Who lead the Persians into a coalition with the Medes, Babylon, Scythians, and Cimmerians to fight against the Assyrians?
All the background I'm provided with is that "Under king Cyaxares, the Medes and Persians entered into an alliance with Nabopolassar of Babylon, as well as the Scythians and the Cimmerians, and together they attacked the Assyrian Empire.". Is that enough to answer the question?
Answer: yes
