Many of the nations in the multipolar alliance have little in common with each other except for their disdain for the U.S. That, however, is a powerful unifying force. From Christopher Roach at amgreatness.com:
The American people’s interests require the dismantling of the American empire
Back in my high-school debating days, policy debate teams frequently concluded their arguments with an extreme and somewhat absurd parade of horribles. This was a testament to their intelligence and creativity, plus being dead wrong carried few consequences. Through convoluted chains of logic, they argued that some small change in environmental or trade policy would lead to nuclear war or America’s domination by the “global south.”
Even then, this all struck me as ridiculous. How could the Third World, with its periodic famines and coups, ever threaten the United States? Back then we were fully dominant over the entire world after the collapse of the Soviet Union and the Warsaw Pact.
A lot has changed.
During the Cold War, the various nations on the periphery acted, in some ways, as judges of the two competing systems. While the United States and Soviet Union were accused of manipulating the Third World for selfish reasons, the manipulation went both ways. Being coy, Third World leaders often managed to squeeze real benefits, like infrastructure projects, discounted military equipment, and other forms of aid by siding with one side or the other.
