Yeah, right. There’s only three players. Now, its the US vs Russia and China.
Both are eternal enemies...
You omit India, which will surpass China in population around mid-century and has a rapidly improving economy and standards of living. India has its own reasons, both historic and strategic, to be concerned about a Russian and Chinese military alliance along its northern borders. It also has reason to be concerned about militant Islamic state and nonstate actors to its west.
It cannot escape its geographic realities and, therefore, is compelled to chart an independent path. A real military alliance with the west, and specifically the United States, is probably a political bridge too far. But it can be encouraged and strengthened to frustrate the military aspects of China’s “belt and road” initiative and strengthened as a naval power so that the Russians and Chinese understand their fleet units are always going to be tolerated visitors in the Indian and Southern Oceans, not permanent residents.
