If we take this report at face value, it tells us that Kissinger, an old cold warrior, is working to use Trump's commitment to better relations with Russia in order to separate Russia from its strategic alliance with China.
China's military buildup is a response to US provocations against China and US claims to the South China Sea as an area of US national interests. China does not intend to attack the US and certainly not Russia.
Kissinger, who was my colleague at the Center for Strategic and International studies for a dozen years, is aware of the pro-American elites inside Russia, and he is at work creating for them a "China threat" that they can use in their effort to lead Russia into the arms of the West. If this effort is successful, Russia's sovereignty will be eroded exactly as has the sovereignty of every other country allied with the US.
