"The Mackinder Heartland Theory, which became Brzezinski's Grand Chessboard, which became the Wolfowitz Doctrine under Bush..."

Ugh, the so-called "geographical pivot". So from a historical perspective, you know that those theories are not only complete nonsense, but the cause of much suffering and death? Not only did the 19th century Heartland theory lead to several pointless and very bloody wars in Asia, but it later became part of the strategic basis of Nazi Germany's eastward push.

This pivot idea has been around a long time and has zero demonstrated merit. Given the historical costs, we should be extremely wary of any world leader who appears to subscribe to it.
