Nope. China and allies vs USA and allies. And it will be decided on who wins the swinging allies. Japan, Europe, Taiwan if it exists, and Australia will side with the US. Russia will side with China, and any risen countries in Africa. India and Brazil are leaning China, but i reckon are still subject to diplomacy. India matters a lot.

The nominally Christian vs nominally Muslim wars have been the primary conflicts since the end of the cold war, but the Ottoman Empire fell in WWI. There's not enough to rise to a significant enemy, and the sunni/shiite rift is too keenly felt for them to jihad together.

World wars happen between the two biggest powers.
