China is on the rise, and is a a great to watch it rise. However let's not kid ourselves with the adoration of China's rise as a economic and military superpower. China's rise on the world stage means an inevitable clash between itself and the old superpower, America. As it the world has already witnessed, America is fighting to keep it's status as the world's pre-imminent superpower. America's status as a "Ruling State," which by definition means America can impose it's will on other countries, unchallenged. This status is now eroding fast, with Russia rising from the ashes of the bogus Soviet Union, like a Phoenix, and China's rise on the world stage as a superpower.
Both Russia and China seek a "multi-polar" world, which in essence is a world without a hegemon.
In order for China and Russia to truly realize the might and power of their militaries. They require allies, not some token agreements or loose alliances. Rather the formation of a bloc of countries which are stable, economically robust and politically bulletproof. These nations can and should be in a formal and stipulated alliance with both Russia and China. Not just economic alliance, but also military alliance, ironclad. If you pick up the map of the world today and correlate the political unrest around the world today in various countries. You will see that Russia's and China's list to choose allies from, is growing smaller by the day. And this does not bode well for either China or Russia.
You can have the largest navy in the world with 20 aircraft carriers and 6000 nukes. But if you don't have allies who are lock 'n' step with you in a fight to the finish against you adversaries. Then I am sorry, but such a power state would see it's demise faster than quicksand. Having a large navy has no impact against an enemy which has Japan and South Korea as it's allies, at China and Russia's doorstep. As their combined effort in the event of a war, is what would tip the scales of the old wood-board superpower, America.
