The BRICS Alliance is nearly equal to the US by older conservative measures. Throw in Iran, North Korea, Venezuela, Equador, Cuba and Bolivia and US hegemony is in sunset mode.
China's military spending is undercounted by a huge amount - and their military advances are alarming the Pentagon. They came up with the DF-21 carrier killer missile and a new hypersonic weapon that the US hasn't developed yet.
China is spending billions across the 'Stan countries ( where 40% of the world's population is) to build a new Silk Road for massive trade movement. They already passed the US this past year in worldwide trade.
China holds 1.3 trillion dollars in reserves. While foolish liberal bloggers worry about the Koch brothers (billionaires) they apparently ignore the fact that China can easily buy all the US politicians they want ( like Senator Harry Reid?).
Today, it was announced that US growth has hit 0.1%. Basically stalled. The BRICs Alliance may have a near monopoly on growth internationally.
China builds and grows while the US tries to start wars - that even Europe doesn't really care about.
Get ready for inflation in commodities (oil, food, etc.) as the US loses currency reserve status and can't flood the world with green paper IOU's anymore. OTOH, the Chinese will probably support higher farmland prices here as the dollars come back.
