Could America break apart? UCSB expert explores the possibility

In a new book, political economist Benjamin Cohen considers the forces driving nations — including the United States — toward fragmentation

Benjamin Cohen begins his new book — his 20^th, if you are counting — with a fictional news dispatch from the year 2035.

“After years of festering discontent with the direction of politics in Washington, California today formally declared its independence as a sovereign nation,” it reads. “President Vance has threatened a military takeover of state government in Sacramento, backed by National Guard troops from nearby red states. Armed conflict looks increasingly possible.”

A provocative scenario, all the more plausible coming at a time when California’s governor is furious at the president for ordering troops into the state to keep order at immigration protests. But for all our partisan acrimony and political polarization, America isn’t really headed towards a second Civil War — right?

“I wish I could be that sanguine about it,” said Distinguished Professor Emeritus Cohen, who spent 30 years as the Louis G. Lancaster Professor of International Political Economy in the Political Science Department at UC Santa Barbara before retiring from teaching in 2021. “I’m not. It seems to me we cannot ignore the risks of the current fissures and fragmentation — the breakdown of a sense of community.”

Given that today’s political divide is more between urban and rural as opposed to North vs. South or East vs. West, “It’s difficult for me to imagine how things would divide up if there were a civil war,” Cohen added. “But the probability of such a war is substantially greater than zero.”

Cohen’s views on the subject are extremely well-informed. His new book “Dream States: A Lurking Nightmare for the World Order” (Oxford University Press, 2025) is a comprehensive guide to secession movements currently active all around the world. He provides an assessment of the risk of these efforts leading to violence, and offers a possible path to diffusing tensions.

“I consider secession a grievously underappreciated phenomenon,” he said. “My motivation to write this book was to call people’s attention to this fact.

“We tend to simplify geography by looking exclusively at the existing lines on a map that separate one sovereign state from another,” he continued. “But the reality is there are many people within those states that are very unhappy with the arrangement. They’d prefer to draw the lines in a different way. In some cases, they’re prepared to fight to redraw those lines.”

Professor Cohen’s publications have addressed issues of international monetary relations, U.S. foreign economic policy, currency integration, sovereign debt, theories of economic imperialism, and the history of the discipline of international political economy. He is the author of 20 books. He…

The war in Ukraine provides a vivid example. The conflict over whether it should be an independent nation or a facet of greater Russia “goes back hundreds of years,” Cohen said. “It’s not going to end with the current conflict.

“It’s similar to the relationship between Quebec and Canada. Quebec is a distinct community, with a different language, which has periodically challenged its incorporation into the larger state. The same is true of Ukraine. A majority of Ukrainians believe they have the right to a state of their own. Putin and his people take a quite different view.”

The difference between the two situations, of course, is that Canada has found a way to keep Quebec in the fold, primarily through allowing the province to have considerable sovereignty over its own affairs (including the use of French as an official language). Cohen sees this sort of compromise — also found in the relationship between the United Kingdom and Scotland, and Spain and Catalonia — as the most promising way to avoid violence.

But it’s simply not happening in most potential trouble spots. The most dangerous of these is surely Taiwan, an island off the Chinese coast that has been independent from the mainland since the end of World War II. “From the point of view of the Chinese government, and probably the Chinese people, Taiwan belongs to China,” said Cohen, who sees the odds of China eventually using force to establish control as “very high.”

“The Chinese are increasingly bold in the waters around Taiwan,” he noted. “They’re gradually encircling the island in anticipation of an eventual embargo, in which ships could not enter or leave. It’s a clever, incremental strategy. At some point, my fear is Taiwan will feel it necessary to resist this by force. That’s when things could get ugly.”

Of course, things are already pretty ugly — not to mention chaotic — in the realm of international trade. Cohen said he has never witnessed anything like the current state of disorder in his lifetime. The closest analogy he can find is the period immediately after World War I which produced the infamous Smoot-Hawley Tariff Act of 1930.

But as Cohen notes, much of human decision-making is driven by forces other than logic. In the case of the secession movements he documents in “Dream States,” the primary driver is usually a sense of identity — the impulse to rally behind the group you feel you belong to, and the insistence on its right to act independently.

“Identity can be a very powerful motivator,” he said. “That’s why I worry about the risk of civil war. When it comes to something as strong as a sense of community identity, rationalism falls by the wayside.”
