New Mediterranean: Become Rome or Perish as Carthage
Prologue: Geographic Convergence and the Birth of the “New Rome”
Mackinder’s “World-Island” theory once treated the Americas and the Eurasian landmass as geographically isolated entities. This assumption provided a critical premise for modern international politics: the United States could function as the archetypal “offshore balancer,” leveraging distance and oceans to intervene in Eurasian power competitions at will, yet always retain the option to withdraw. However, as the Arctic ice barrier physically disintegrates, this very premise is becoming obsolete.
The Arctic Ocean is no longer a boundary between civilizations and powers; it is rapidly transforming into a “New Mediterranean” connecting the Americas and Eurasia. In physical terms, the Americas are no longer an isolated island offshore, but have achieved substantive spatial convergence with the Eurasian landmass via the North Pole, forming a closed and contiguous “Global Landmass.”
On this rewritten map, the question is no longer whether the United States chooses to enter the arena, but whether the spatial structure still permits it to remain outside. The heightened strategic attention Washington has paid to Greenland in recent years is not a momentary impulse, but a structural necessity pulling America into the field under the reality of geographic convergence. For the United States, entering now still allows it to secure a native position; if it refuses or delays, other powers may establish bridgeheads around the American periphery, at which point the U.S. would not merely lose its status as a balancer—it would lose even the starting position from which to help write the rules.
Act I: Power Positioning and Strategic Misalignment Under Spatial Compression
As the “New Mediterranean,” the Arctic’s central contradiction lies not in the shipping lanes themselves, but in the indeterminacy of its spatial character: Is it an open sea, or an inland sea effectively controlled by a handful of great powers? Before its legal character is settled, the Arctic constitutes a classic power vacuum.
In this scramble for position, states with long Arctic coastlines and sustained physical projection capabilities—principally Russia and the United States—naturally form an exclusive “quasi-proprietor structure.” The Arctic reveals a primal trend: international politics is regressing from “rule competition” to “spatial positioning.” Rules are no longer the prerequisite for entering a space; they are the consequence of having already occupied it.
The situations and choices of China and Russia constitute the most direct source of pressure for America’s entry. Russia, with its extensive coastline and nuclear icebreaker fleet, enjoys first-mover advantage in physical positioning. By contrast, China highlights a congenital deficiency in geopolitical structure: with no territorial foundation in the Arctic, it fundamentally lacks natural footholds from which to insert itself.
Yet China’s true strategic error lies not in the absence of footholds, but in a severe misalignment of positioning. Faced with a power vacuum, China has invoked its status as a “near-Arctic state” to deeply bind itself to Russia through capital and infrastructure, promoting the “Ice Silk Road.” This has not only failed to yield substantive spatial control, but has prematurely exposed its intentions, deeply offending the United States, which holds core security claims in the Arctic. China could have leveraged its vast economic and shipping influence to maintain flexibility between the U.S. and Russia, even acting as a counterweight to Russia’s exclusive “quasi-proprietor” status on specific issues. Instead, China made a bad bet by deeply binding itself to Russia’s unilateral advantage—not because Russia’s hand was inherently superior to flexible diplomacy, but because China failed to see that the chips it could originally have held for competitive bargaining had already been foreclosed by that very binding.
This strategic misalignment, combined with Russia’s first-mover advantage, accelerated America’s strategic awakening. When the United States observed Eurasian powers attempting to solidify the “New Mediterranean” into an exclusive inland sea, its structural pull into the arena became a foregone conclusion.
Act II: The Disenchantment of Sovereignty and the Legitimization of the “Feudal Structure”
Up to this point, the discussion has remained within a classical framework: who occupies which space. But this only explains why the vacuum appeared, not how it will be filled. The physical convergence in the Arctic triggered the crisis, but what fills the vacuum is not traditional exclusive territorial competition. It is a relational structure that has long existed yet been consistently masked.
The international order established after World War II is superficially founded on “sovereign equality”—one state, one vote in the United Nations; every signatory of the UN Charter is presumed to be an equal and complete sovereign entity in law. Yet this legal shell was disconnected from operational reality from the very beginning. America’s nuclear umbrella, forward military deployments, and the global dependency system of currency and technological standards have embedded Europe, East Asia, and even peripheral territories like Greenland into an asymmetrical relationship of protection and allegiance. The center provides protection and recognition; the local actors, while offering allegiance, retain wide de facto autonomy over their own affairs. The cost of that allegiance is often far lower than the protection and autonomy gained from the relationship.
This is precisely why the system has remained unnamed for so long: ambiguity benefits both sides. The center (America) enjoys protection extended without formal obligation, adjustable unilaterally at any time. The local actors (Europe, Greenland, and potentially Alberta) save on defense expenditures commensurate with their own size, redirecting resources toward domestic and industrial policy. No one has had an incentive to expose this arrangement—until external pressure made the cost of maintaining ambiguity exceed the benefits for the first time.
The physical convergence of the Arctic is precisely such an external pressure. It makes a node like Greenland, long suspended in ambiguity, face for the first time the real risk of being seized by another; and it gives a periphery like Alberta—already attached to the Canadian federation yet resentful of Ottawa—concrete incentives to renegotiate its alignment. Once ambiguous zones become objects of others’ desire or opportunities for renegotiation, the cost of willful blindness becomes uncontrollable—and the system is forced onto the table for re-contracting.
The underlying logic of this forced revelation points directly to the normal state of pre-modern politics: it is no longer the flat management of a modern republic based on legal equality, but a regression toward a “feudal overlord” system filled with compromise, flexibility, benefit-sharing, and personal dependency. The closure of space is stripping away the disguise of modernity. The real question to be addressed next is no longer “how should America occupy space,” but “how should a feudal relationship that has long existed without proper recognition or legitimacy be formally acknowledged and recalibrated in rights and obligations.”
Act III: Substantive Legitimization—The Dual Solution of Greenland and Alberta
Once the old framework of “indivisible sovereignty” is broken, the dilemma of spatial positioning resolves itself. Greenland and Alberta are precisely the two nodes where the old structure is forced to reveal itself and demand legitimation.
Greenland: From Ambiguous Dependency to Functional Trusteeship
Greenland controls the GIUK Gap leading into the North Atlantic. It is the critical gate through which the American landmass enters the core of the “Global Landmass.” Denmark’s projection capability in the Arctic direction is limited. One might ask: Why not simply follow the Cold War model of Thule Air Base—achieving equivalent strategic effect through deeper NATO joint defense agreements while leaving Danish sovereignty intact? This option worked in the past, but under the new pattern of “real-time positioning at core nodes,” the decision lag inherent in traditional alliance-based deployments—where any major deployment still requires Danish sovereign consent and domestic political procedure—may no longer match the speed of spatial competition. Decision lag itself constitutes a strategic risk.
The Greenland problem was deadlocked because it was posed within the old framework of “indivisible sovereignty.” But if sovereignty can be functionally divided, much like the non-exclusive arrangement between center and local strongman in a feudal structure, “belonging” becomes a bundle of separately negotiable relationships. America’s conception is not traditional territorial expansion, but a form of “functional trusteeship”: Greenland maintains nominal autonomy, while ceding control of defense and strategic resources to Washington. This is not the invention of a new relationship, but the formal legitimation of a dependency structure that has long existed. Once divisible sovereignty is accepted, the “Greenland problem” ceases to be a logical contradiction and becomes a bargaining question determined by the balance of power.
Alberta: The Same Solution, at a Different Periphery
Alberta’s separatist stirrings reveal that the North American interior is being drawn into the Arctic strategic perspective. If Alberta were to form a highly integrated defense relationship with the United States, it would provide Washington with a secure land corridor running from the North American heartland straight to Alaska, giving its Arctic presence sustainable inland support.
Alberta is currently trapped in the same dead end of “indivisible sovereignty”: Ottawa habitually reads any deep integration as a zero-sum choice between separation and annexation. Yet Alberta’s energy and industrial chains are already deeply bound to the American market. This de facto dependency is far more real than its federal relationship with Ottawa. Under a framework of divisible sovereignty, energy and defense allegiance could shift separately toward Washington, while cultural and domestic nominal ties could be preserved. This is essentially the same template as Greenland, only with a different periphery and suzerain.
This inland turn signals that America is collapsing from a traditional offshore balancer into a competitor that must be physically present. In a world of closed space, failure to occupy a corridor means having it occupied by another.
Finale: Who Is the New Rome? And the Coronation of the “Feudal Overlord”
The future character of the Arctic “New Mediterranean” will be determined by the status quo of physical occupation. Geographic convergence has ended not only America’s security dividend, but the very spatial conditions for its role as an “offshore balancer.”
In this forced entry, history’s Mediterranean has given us a deeply deceptive answer. It is worth noting that both Carthage and Rome were republican systems. Even on the eve of Carthage’s destruction, Rome was still far inferior to Carthage in aggregate power and prosperity. Carthage was the true commercial hegemon; its network was nothing but a transaction from end to end: Numidian cavalry, Iberian mercenaries, all loyal on fair-weather days, but at the Battle of Zama, the moment the wind turned, they all defected to the other side. Because Carthage never gave them identity—only payment.
Where Rome won was not merely in its understanding of how to endow loose dependencies with legal status and a sense of identity. More importantly, it ultimately moved toward a highly flexible “plural overlord” structure. It never pursued Louis XIV-style absolute centralization. Instead, through “client kingdoms,” allies, provincial governors, and local aristocracies, it constructed a vast “feudal” network. Rome’s greatness lay precisely in its capacity as a “feudal overlord” to use compromise, benefit-sharing, and personal dependency to maintain the low governance costs of a vast realm.
Today, on the ice fields of the Arctic, this contest between Carthage and Rome is being replayed. America’s post-WWII global system is essentially more inclined toward Carthaginian commercial transaction; Russia is attempting to use “Grand Space” theory to assume the Roman role of establishing an exclusive order.
But in this contest, there is a cruel iron law long obscured by modern political science filters: Carthage ultimately fell to the divisions and internal strife of its republican system; therefore, whoever can first crown a new monarch will be the ultimate winner.
Here a fatal misconception must be clarified. When modern people hear “monarch,” what comes to mind is often an absolutist like Louis XIV or Kangxi. But in the high-complexity, high-stakes “New Mediterranean” game, the state that first moves toward absolute despotism will perish from its information cocoon and strategic blindness.
The “new monarch” I speak of is precisely the true historical norm—the “feudal overlord” that emerged from European feudal estates and similar systems of layered authority. He is not an omniscient, omnipotent dictator, but the “first among equals,” the overlord of the alliance.
Only this kind of “feudal overlord” can perfectly match the strategic demands of the “New Mediterranean”:
He understands how to abandon the modern fastidiousness of “indivisible sovereignty” and accept “functional trusteeship” without compunction. He understands how to engage in benefit-sharing and power-sharing with Greenland’s local representatives and Alberta’s energy oligarchs. He can maintain the long-term strategic vision of the empire while, through co-governance with aristocrats and power brokers, preserving the system’s error-correction capacity and feedback mechanisms.
Whether America’s current push for “functional trusteeship” in Greenland and Alberta represents an awakened turn toward Romanization, or the final struggle of a Carthage before collapse, depends on whether Washington can complete this transformation in the anthropological sense of politics: shedding the modern disguises of “absolute republic” and “sovereign equality,” and candidly donning the crown of the “feudal overlord.”
When space converges, the offshore balancer must be physically present. But the one who ultimately establishes enduring hegemony on the ice fields will not be an omniscient, omnipotent dictatorial empire. It will be a “New Rome” stitched together bit by bit from the allegiance, compromise, and interest compacts of countless local representatives.
Whoever can first complete this coronation of the “feudal overlord” will be the one who, on the battlefield of Zama when the wind turns, leaves those peripheral nodes with no option to defect. Because in that moment, they will no longer be mercenaries working for pay, but feudal vassals sharing weal and woe with their overlord.
This is the final riddle of the New Mediterranean.
