The U.S. has accelerated a process that’s been underway for many years. From Michael Hudson at unz.com:
Empires often follow the course of a Greek tragedy, bringing about precisely the fate that they sought to avoid. That certainly is the case with the American Empire as it dismantles itself in not-so-slow motion.
The basic assumption of economic and diplomatic forecasting is that every country will act in its own self-interest. Such reasoning is of no help in today’s world. Observers across the political spectrum are using phrases like “shooting themselves in their own foot” to describe U.S. diplomatic confrontation with Russia and allies alike.
For more than a generation the most prominent U.S. diplomats have warned about what they thought would represent the ultimate external threat: an alliance of Russia and China dominating Eurasia. America’s economic sanctions and military confrontation have driven these two countries together, and are driving other countries into their emerging Eurasian orbit.
American economic and financial power was expected to avert this fate. During the half-century since the United States went off gold in 1971, the world’s central banks have operated on the Dollar Standard, holding their international monetary reserves in the form of U.S. Treasury securities, U.S. bank deposits and U.S. stocks and bonds. The resulting Treasury-bill Standard has enabled America to finance its foreign military spending and investment takeover of other countries simply by creating dollar IOUs. U.S. balance-of-payments deficits end up in the central banks of payments-surplus countries as their reserves, while Global South debtors need dollars to pay their bondholders and conduct their foreign trade.
This monetary privilege – dollar seignorage – has enabled U.S. diplomacy to impose neoliberal policies on the rest of the world, without having to use much military force of its own except to grab Near Eastern oil.
