CU alumâs book examines how the fate of the Netherlands, Great Britain and the United States as economic and political powers has been deeply intertwined with their ability to project power via the seas

Itâs a topic beyond simple academic interest to Flint, who was born in 1965 and raised in England during a period of seismic change in the country.
âAt the time, Britain was still struggling to figure out that it wasnât the worldâs greatest power anymore, so my socialization and political coming of age was in a declined power,â he says. Additionally, Flint says being raised in the busy ferry port of Dover made a powerful impression on him by highlighting the countryâs long history as a maritime nation.

Colin Flint, a CU Boulder PhD geography graduate, researches the rise and fall of great world powers.
âDover definitely has influenced me, being so close to the water,â he says. âMy high school was on a hill overlooking the harbor, which at the time was the busiest ferry port in the world, with ships going back and forth to France and Belgium. So, the notion was very much rooted in me that Britain drew its power, historically, from the sea.â
At one point, Flint entertained the idea of joining the Royal Navy before setting his career sights on academia. He obtained his bachelorâs and masterâs degrees in Britain, then pursued his PhD in geography at the °ľÍř˝űÇř thanks to fortuitous connections between his undergrad mentor and CU BoulderĚýDepartment of Geography Professor John OâLoughlin.
âI moved to United States of America in 1990 to attend university, and the literature at the time and discussions were all very declinist. It was very much, âAmerica has gone down the tubes,ââ he says. âBroadly speaking, I moved from a declined power into a declining power, or so I thought at the time.â
After the fall of the Soviet Union, Flint says the idea of America as a declining power was largely replaced with a triumphalist narrative that saw the U.S. as the worldâs only remaining superpower.
Ideas about what makes a country an economic and political superpowerâand how a country can lose its status as aĚýâhad been percolating in Flintâs brain for years when he recently published his bookĚý. The book specifically looks at the Netherlands, Great Britain and the United States for context on how the countries used sea power to project their economic and political influence across the globe.
Flint spoke with Colorado Arts and Sciences Magazine about his book, while also offering insights on how current events are shaping the outlook for the United States and the world. His answers have been edited for clarity and condensed.
Question: What is the context for your bookâs title:ĚýNear and Far Waters?
Flint: There are legal terms about coasts and the exclusive economic zone around the countryâs coastlines, but Iâm not using it in that way. Iâm thinking about an area of ocean in which a country has interest and influence over and off its coastline.

"Near and Far Waters" by CU Boulder alumnus Colin Flint focuses on the Netherlands, Great Britain and the United States for context on how the countries used sea power to project their economic and political influence across the globe.Ěý
That is an important piece of ocean for a country because thereâs resource exploitation, but itâs also a matter of security. If a country wants to protect itself from potential invasion, it needs to control those waters off its coastlineâitâs near waters.
Some countries, once theyâve established control of their near waters, have the ability and desire to project beyond that, across the oceans into what would then become its far waters. If you think about Great Britain in the context of the British Empire, once it fought off European threats to its coastlineâits near watersâit was then able to develop the sea power to establish its empire. It was in African far waters, it was in Indian far waters, in Middle East far waters and so on.
Another good example of this would be how the United States of America, over the course of history, pushed other countries out of its near waters. The Caribbean and Gulf of Mexico are good examples, where Spanish and British influence were ended over the 1800s and 1900s. And then by establishing control through annexation of Hawaii and the purchase of Alaska, America developed its Pacific near waters, too, which it expanded upon through the course of World War II, pushing the Japanese back and establishing bases in Okinawa, Japan; the Philippines; and Guam, etc.
Question: One of your chapters is titled âNo Island is an Island.â What do you mean by that?
Flint:ĚýI was talking about how the projection of sea power requires the control of islands. Often, the geopolitical goal and benefit of controlling an island is not the island itselfâitâs how it enables projection of power further, or how it hinders other countriesâ projection of power by being near sea lines of communication that you can have a base to try and disrupt. For example, when Hawaii became part of the United States, it allowed the U.S. to project power across the Pacific. Again, itâs not the island itselfâitâs the projection of power across an ocean.
Projecting sea power is about more than just having a strong navy.
Question: If one countryâs far waters extend into the near waters of another country, that would seem to be a recipe for conflict, would it not?
Flint: That is the kicker, of course, that a sea powerâs far waters are another countryâs near waters. And it has historically led to conflicts and even wars. Itâs always involved violenceâand not just between great powers and lesser powers, but also violence against the people living on islands or in coastal lands where sea powers are looking to establish dominance and exploit resources.
Question: China has been rapidly expanding its navy in recent years. Is it simply beefing up its sea forces to protect its near waters, or is it looking to supplant the U.S. as the dominant sea power? Or are there other motives at play?
Flint:ĚýYou often see in newspaper articles written in the United States and maybe other Western countries that China has the biggest navy in the world. This always makes me laugh because, yes, itâs got hundreds and hundreds of tiny little coastal defense vessels, but even now that it has two aircraft carriers, it does not have the ability to project power like the United States of America, which has 11 carrier groups. So, I think that should always be recognized.
The other sort of trope thatâs often wielded out there, which I think we need to question, is: The West is worried about China developing a navy, because it will allow China to disrupt trade networks. Well, wait a minute. China is very dependent on imports, especially of fuel or energy. Additionally, it is the worldâs largest trading economy, and itâs worried about the robustness of its domestic economy. They cannot maintain their economic growth based purely on their domestic market, so they need to have a global economic presence for markets and for securing inputs into their economy.
Putting those two things together, it makes no sense why China would want to disrupt global trade. In fact, the countryâs reaction to President Trumpâs sanctions tells us that the last thing China wants is global trade disrupted. Theyâre very worried about the fragility of their own economy and whether that leads to social unrest, etc. The flip side of that is how the West could really hurt China by blocking those trade routes to prevent energy imports into China and exports.
China is definitely trying to grow its navy. I think what makes it so interesting is its simultaneous attempt to have a navy that can defend its near waters while perhaps preventing the operation of the United States in its far waters. To what extent China is attempting to establish a presence in its far waters is less clear.

"A sea powerâs far waters are another countryâs near waters. And it has historically led to conflicts and even wars," notes scholar Colin Flint. ("Naval Battle of 1812," Painting, Oil on Canvas; By Rodolfo Claudus; 1962/U.S. Naval History and Heritage Command)
Question: From your book, it seems like you have some serious concerns about the potential for a serious conflict arising from disputes over near and far waters?
Flint:ĚýIn fact, Iâve never been so concerned or worried in my career, to be honest with you. When I started teaching my class on political geography many moons ago, letâs say in the mid-1990s, I used to start off with some structural model of global political change, which essentially says, we have cycles of war and peace, for the want of a better term.
And I asked my students to try and get them engaged: âPicture yourself in 2025. What are you going to be doing?â It was staggering to me how many of them believed that they would be millionaires and already retired (laughs).
The point of that was that the model I was using predicted another period of global war, starting in 2025. I donât do that exercise anymore, because it isnât funny; itâs really quite serious. So yes, the risk of war is high, and I think it could emerge in a number of different places. One focus is on the South China Sea, the near waters of China, as that is clearly a potential flashpoint. Taiwan is the obvious focal point of what that conflict would look like.
I also wonder about potential flashpoints of conflict in Chinese far watersâand that could include the Arctic and the Northern Atlantic, because another factor that has to be considered is global climate change and the increasing possibility of a trade route through the North Pole, which would cut trade times from China into European markets considerably. Those waters represent U.S. near waters, so âŚ
Question: Do you envision any sort of viable alternatives to a conflict between world powers over near and far waters, especially in todayâs environment?
Flint:ĚýMy motivation with the book was with an eye to waving some sort of flag about how to think about peace rather than war. Most of our lenses are national lenses. If we keep on this pattern of a national lens, then I see a strong likelihood to repeat these cycles of near and far water sea powers, which have always involved a period of global war.
We need to change that lens. We need to have a global view as to why countries are always seeking far waters, entering other peopleâs near waters and why that can lead to conflict.
Today, weâre facing a humanity-scale problem, which is global climate change. Is that the thing that will tell us we need to work together, rather than compete? Iâm not saying it is; Iâm saying, if I see a glimmer of optimism to your question, thatâs it.
Question: Based upon your research, if a country loses its status as a hegemonic power, can it later recover that status? And, in the context of todayâs world, what might things look like if the U.S. lost its hegemonic status?
Flint: The short answer is no, based upon past history, a country that loses its hegemonic status has not been able to reclaim it once itâs gone.
But to your second question, it goes back to the question about what Chinaâs intentions are. In American popular culture, where every sports team has to be No. 1, even if they are eighth in some Mickey Mouse conference, there is this obsession that there has to be a singular winner or champion.
What Iâm saying is that we shouldnât just assume that if the United States declines there will be another emergent dominant power in the world. Itâs quite possible that if the United States declines, what might emerge would be a multipolar world, although I donât know what that might look like.Ěý
