In 1972, before then-US president Richard Nixon’s visit to China, US national security adviser Henry Kissinger was expounding his “balance of power” theory. This saw the US working with China to keep the Soviet Union in check over the next 15 years. Another 20 years on, the US president has changed tack, teaming up with Russia against China.
This rotation of the triangle of relations between the three powers took place almost 20 years later than Kissinger had predicted, but now we have US President Barack Obama’s administration concentrating once more on US-Russia relations: They recently signed the first nuclear weapons pact between the two countries in two decades. The US has clearly decided its best bet is to lean toward Russia to keep China under control.
