The U.S. “empire” grew primarily out of WWII and the later collapse of the Soviet Union. The democratic and representative republics in West Europe and Japan and eventually South Korea and Taiwan and Eastern Europe and other places as well are now internally stable allies (and often economic competitors) of the U.S.A. This would all have been inconceivable without Wall Street, U.S. capitalism, and our military state power exercised overseas.
Over most of this whole period the U.S. standard of living continued improving dramatically, as did technology, science, and average life quality, while whole previously segregated and oppressed sections of society were integrated and given equal civil rights.
New problems we have, of course. But our national power and economic power were crucial to world development in preventing fascism and far worse forms of imperialist oppression. Our “empire” is not colonial and has allowed for some even non-democratic societies to develop dramatically … while most Americans hoped that would change them internally. Not everything works out as we would like, but we should not get hysterical about setbacks or seek imaginary partisan scapegoats.
Even in our traditional Monroe Doctrine backyard, South America, there are today developing countries that are integrated (if necessarily subject) parts of the world capitalist empire (trading with China) that the U.S. is struggling to remain in control of. Mistakes have been made. A few horrendous wars we have engaged in unnecessarily. We are still arrogant and often too quick to bully and sanction. But the U.S. “empire” abroad has been far better than those that would have and indeed partly were imposed by Hitler, Stalin and Japan.
Was our “Deep State” Wall Street empire wrong when Eisenhower was a Five Star General imposing by force U.S. power? Should he and it have laid down before Hitler, then Stalin? In 2022 should we have done nothing in the face of Putin’s invasion of independent Ukraine? Can we simply beat our swords into plowshares today?
P.S. I’ve always admired Eisenhower for his warning during the Cold War about the threat to our own democracy constituted by a huge Military Industrial Complex. Of course that didn’t prevent him from making his own mistakes, for example in Indochina, where his Cold War instincts led him to support total financial and military aid to the French, after to reject a popular vote that would have led HoChiMinh to take power, and then led to our own calamitous Vietnam War.
