Wars are costly. Very intensive and extensive in the use of resources and the destruction of resources; let alone the loss of quantity and quality of life.
In all wars, all parties incur costs; significant costs. Sometimes, a party to a war can avoid most of those costs through having someone else pay. Of course, the United States paid to some extent for the wars against Iraq in terms of American lives lost and degraded; little cost was borne by those Americans who propagated those wars, though.
The material costs of the wars in the 2000s were paid – indirectly – by Chinese households not consuming large swathes of the goods they produced; Chinese workers and capitalists were, on an increasingly massive scale, exporting the fruits of their labour and their capital to the United States. More sending than spending. Much more. (A Marxian analysis would attribute the seemingly costless affording of the US-Iraq war to the extraction of ‘surplus value’ from the Chinese working class by the American capitalist class.)
Yet these Chinese costpayers didn’t much mind, because – while their abilities to enjoy the increasing fruits of their labours were highly constrained by China’s export policy – they were happily stacking up claims on future production; deferred enjoyment, rather than the pure exploitation which occurred in the early years of Chinese Communism.
China bore the West’s costs in other ways too; in those years Chinese people suffered huge environmental costs, at a time when natural environments were improving in the deindustrialising West.
There was a wider set of ongoing costs, however, arising from the ensuing highly unbalanced global capitalism. United States’ industrial survival is now largely dependent on its specialisation in military hardware and software; meaning that the United States’ economic deformation has made that country into a predatory warrior state. Violences, especially upon non-Americans, are today directly committed by the American state; and through both exported and gifted military goods and services, and through violations committed directly by America’s proxies (and, as in Sudan, by its proxies’ proxies).
