An old geopolitical theory whose weaknesses were exposed in both World Wars. The Russians don’t even follow it anymore; they are more enamored with Alexander Dugin’s theories nowadays.
Yet China seems to be dead serious on enacting that geopolitical idea to some extent, per their Belt and Road Initiative.

That’s seriously not a serious reply. I don’t blame you, this part of reality is not taught at all in any schools from K to PhD.
Mackinder wrote his seminal paper circa 1903, when the Tsars ran Russia. His theory outlasted Communism in the USSR from 1917 to 1991. It will outlast the ChiCom CCP. It is a geopolitical reality like gravity.
That is the real game. Not one in 10,000 get it. Including PhDs.
