How will/should the greatest powers align themselves?(China, India, Russia, USA)

[Wikipedia delenda est]

I think China and Russia will probably end up on the same side, considering their joint enmity toward the United States. With a friendly China, Russia won't need to support India anymore, meaning India might turn toward the US and Japan. The US then might become more pro-India on the Kashmir question, pushing Pakistan away from the Americans and Saudis and toward Iran. Turkey, I think, would ultimately side with the US and allies, reluctantly ending its flirting with Russia and fulfilling its obligations as a NATO ally. Even though Turkey dislikes the Saudis due to Khashoggi, they'd most likely return to their side in the event of a war considering that Assad, their sworn enemy, is supported by the Iranians.
