An Americas-centric map;



also showing the US pivot to the Pacific which is more than a century old (shown more clearly in the larger version); and showing Astan, Pstan and India to the edge of the radar screen.

An Eurasia-centric map:



based on Mackinder's 1904 Heartland and Geographical Pivot of History, who left us this 1919 ditty:

Who rules East Europe commands the Heartland;
who rules the Heartland commands the World-Island;
who rules the World-Island controls the world.
(Mackinder, Democratic Ideals and Reality, p. 106)
I believe it fair to assert that Mackinder's worldview has been accepted (in variants) by Huntington, Kissenger, Brzezinski and Rice; as well as by most of the American political elite.

Mackinder's basic concept is very well-accepted in Eurasia, though in particular versions in state geopolitics (British, French, German, Russian, etc.).

In fact, there is even a Pakistani version by Brig. Nadir Mir, Pakistan and Geopolitics and User:Nadir Mir, which appears to me an attempt to make the case for a larger Pakistani regional presence (hegemony ?). It may be of more interest to others here than to me.
