Are we really Prisoners of Geography?

The piece mentions Sir Halford MacKinder, GA President in 1916.

In a 1904 paper, The Geographical Pivot of History, Mackinder gazed at a relief map of the world and posited that history could be seen as a centuries-long struggle between the nomadic peoples of Eurasia’s plains and the seafaring ones of its coasts. Britain and its peers had thrived as oceanic powers, but, now that all viable colonies were claimed, that route was closed and future expansion would involve land conflicts. The vast plain in the “heart-land” of Eurasia, Mackinder felt, would be the centre of the world’s wars.

Definitely a theme worth discussing to this day...

Recent events in Ukraine can be discussed with reference to this.
