Nixon understood this and played the "China card" by triangulating against the USSR thru 'ping pong' diplomacy.
I'm old enough to remember this and it was a successful policy for decades
we could do the same thing again against China, but Russiaphobia drives our policy and is ingrained in our intelligence analysis....so we expand NATO ( and pay the costs and materials) when instead
we should be expanding forces in the western Pacific, and trying to compete in Africa for resources
I see everything from "All hope for us in Africa is already over" to "Hold the phone, China is bungling, we still have a shot".
Do you know the truth?
