It's clear that capitalist ruling classes who control the US/Anglo/Zionist Empire don't want a shooting war that would destroy much of their assets, but choose to defend their Empire's domination of the world by waging economic war using their control of the world's primary currency, the US dollar.
I think the directors of this capitalist Empire are desperately trying to find some way to maintain their control over the world and this is another way. But, will it work? And, what will be the consequences for ordinary people of the world who always suffer when capitalists inevitably resort to war as a means to secure their domination?
Engdahl doesn't report this, but instead places emphasis on the economies of Eurasia if the Empire wins:
If Washington succeeds on November 4 in cutting all Iran oil exports, world (dollar) oil prices could soar above 100 dollars, adding dramatically to the developing world dollar shortage. This is war by other means. The Fed dollar strategy is acting now as a “silent weapon” for not so quiet wars. If it continues it could deal a serious setback to the growing independence of Eurasian countries around the China New Silk Road and the Russia-China-Iran alternative to the dollar system. The role of the dollar as lead global reserve currency and the ability of the Federal Reserve to control it, is a weapon of massive destruction and a strategic pillar of American superpower control. Are the nations of Eurasia or even the ECB [European Central Bank] ready to deal effectively? [my insertion]I seriously doubt that the Empire will win this war of desperation. But what is not in doubt in my mind is that we humans are doomed anyway through the machinations of our capitalist masters and our failure to take power away from them. That means to deprive them of the ownership and control of our economy and most of the world's economies.
One true prophet of our failure dates back to the 1960s and 70s--Phil Ochs. Examine his statements that often made it into his songs about our future. He is said to have committed suicide, but informed people dispute that. Could his death be another illustration, among many, of Sen. Chuck Schumer's warning that those who cross the CIA, the Empire's secret organization has many ways to punish them?
