You better be right - because if Russia forms a alliance with China, then the US are done. The country with the biggest natural rescources and the country with the biggest manufacturing capacity and influence in Africa ect.
The USA can then stick their Petro-Dollar where the sun doesn't shine - if you want to buy something from Ruscina you have to pay in gold or something else with real value. And just watch how quickly the EU will become good friends with them, to keep the show running.
The only means of countering such a move for the USA would be its military might. But again - the US against Russia and China simultanously? What could go wrong then...
