Michael T. Klare's book "Resource Wars: The New Landscape of Global Conflict" argues that future wars will be fought primarily over access to dwindling natural resources rather than ideology. It is inline with my view that economic consequences speaks louder than ideology. When a group of people is starving to death, faith and ideology doesn't really matter at that time, staying alive is.
Klare contends that in the early decades of the new millennium, competition for vital resources like oil, natural gas, minerals, and water will become the dominant cause of global conflicts. He suggests that the political divisions of the Cold War have given way to a worldwide scramble for these precious commodities. Of those which effect can be seen quicky is energy, which in this era translates to oil.
Klare's argues that resource security is becoming a primary objective for armies worldwide. And the areas where competition for essential materials overlaps with long-standing territorial and religious disputes are likely to experience widespread instability. Identity politics can be easily played in the territory to emphasize the differences and division.
The conflict between the United States and Islamic extremism can be seen as a consequence of consumer nations seeking to protect vital resources. This trend is not limited to the United States but extends to other major powers like China, Japan, and Russia. The stronger one country became, the bigger appetite to take control of beneficial production materials or facilities.
Klare recommends that American national security policy has been focusing on "oil field protection, the defense of maritime trade routes, and other aspects of resource security".
Water scarcity in Africa and some Middle East countries proved a historical problem which easily escalates into conflicts, both diplomatic and military. Tribes has been putting effort to take control of water body, fresh or salty, clean or contaminated. Nowadays it is a matter of nations. The South–North Water Transfer Project in China may be considered a successful project to tackle water scarcity, but with an enormous economic sacrifice and strong political will. This kind of project would probably not work if it engages different soverignty.
Klare's work provides a materialist perspective on international security affairs, emphasizing the industrial and economic dimensions of national security. While some critics argue that Klare may underestimate the potential for diplomatic, economic, and political solutions to resource conflicts, his book offers valuable insights into the geographic and historical factors that contribute to resource wars.
