Certainly the U.S. has self-serving economic interests there, but as I said...it's all much more complex than that. It is a "chess" game, but with MANY players. I think people would find the whole book very interesting...even if they disagree with the mindset or strategies of our leaders.
Some parts are a bit dated already.
Here is the general geostrategic premise for our presense in Eurasia, as outlined in the second chapter under Geopolitics and Geostrategy:
http://book-case.kroupnov.ru/pages/library/Grand/part_2.htmFOR AMERICA, THE CHIEF geopolitical prize is Eurasia. For half a millennium, world affairs were dominated by Eurasian powers and peoples who fought with one another for regional domination and reached out for global power. Now a non-Eurasian power is preeminent in Eurasia—and America's global primacy is directly dependent on how long and how effectively its preponderance on the Eurasian continent is sustained.
Obviously, that condition is temporary. But its duration, and what follows it, is of critical importance not only to America's well-being but more generally to international peace. The sudden emergence of the first and only global power has created a situation in which an equally quick end to its supremacy—either because of America's withdrawal from the world or because of the sudden emergence of a successful rival—would produce massive international instability. In effect, it would prompt global anarchy. The Harvard political scientist Samuel P. Huntington is right in boldly asserting:
--
A world without U.S. primacy will be a world with more violence and disorder and less democracy and economic growth than a world where the United States continues to have more influence than any other country in shaping global affairs. The sustained international primacy of the United States is central to the welfare and security of Americans and to the future of freedom, democracy, open economies, and international order in the world.1--1. Samuel P. Huntington. "Why International Primacy Matters," International Security (Spring 1993):83.
In that context, how America "manages" Eurasia is critical. Eurasia is the globe's largest continent and is geopolitically axial. A power that dominates Eurasia would control two of the world's three most advanced and economically productive regions. A mere glance at the map also suggests that control over Eurasia would almost automatically entail Africa's subordination, rendering the Western Hemisphere and Oceania geopolitically peripheral to the world's central continent (see map on page 32). About 75 percent of the world's people live in Eurasia, and most of the world's physical wealth is there as well, both in its enterprises and underneath its soil. Eurasia accounts for about 60 percent of the world's GNP and about three-fourths of the world's known energy resources (see tables on page 33)......cont'd
