The Mecca Agreement and the Age of Corridorland
Dr. Nurfer TERCAN
The world sometimes changes with a war. Sometimes with a technology. And sometimes with a single agreement.
To read the joint defence agreement signed today in Mecca between Türkiye, Saudi Arabia and Pakistan merely as a text that strengthens military cooperation among three countries would be to fail to hear what history is whispering to us. For great transformations most often begin not with noise, but with the ink beneath a signature. Westphalia was a peace treaty; it left the modern state in its wake. Sykes-Picot was a few lines; it drew the fate of a century. The signature put down in Mecca today may likewise be the first sentence of a question larger than it appears.
The real question is this: Could this agreement be one of the first stones of the new geopolitical architecture of the 21st century?
The answer to this question is hidden not only in defence policies, but in the energy transition, in transport corridors, in climate diplomacy and in the weave of new economic networks. For the world is now passing from the geopolitics of the age of oil to the geopolitics of the age of connections. The measure of power is changing. Yesterday it was the size of the land; today it is the continuity of the flow. Yesterday it was how much underground wealth a country possessed; today it is through which lines, with what assurance and with whose permission it can move that wealth.
Two great theories, one missing equation
A century ago Halford Mackinder said that the heart of the world beat in the inner continent of Eurasia. According to him, whoever ruled Eastern Europe commanded the Heartland, whoever ruled the Heartland commanded the World-Island, and whoever ruled the World-Island commanded the whole world. It was the age of land power; the age of railways, of wide plains, of inaccessible depths.
Nicholas Spykman, for his part, turned the equation upside down. He argued that what was decisive was not the inner continent but the coastal belt surrounding it, the Rimland. This marginal line, stretching from Europe to the Middle East, from the Indian subcontinent to the Far East, was where both sea and land met. Whoever controlled the Rimland would rule Eurasia, and whoever ruled Eurasia would hold the destiny of the world in his hands.
Today, however, neither the Heartland alone nor the Rimland is sufficient. The twentieth century set these two theories against each other; the twenty-first century is obliged to reconcile them. For there was something both of them silently assumed: possession. To possess the land, to possess the coast, to possess the resource. Yet the power of our age has to do less with possessing than with connecting. It is no longer enough to possess a resource; one must be able to connect it, without interruption, to a market, a port, an industrial basin.
That is why today we need a third concept. I call it ‘Corridorland’.
Corridorland: The age of those who connect!
Corridorland is not a piece of geography; it is a capability. It is the new strategic space formed by states that can stitch the Heartland’s depth of production to the Rimland’s openness to the sea; that can carry energy, data, goods and trust along the same line. The borders of Corridorland are not on the map, but wherever the flows pass. It has no capital; it has nodes. Its army protects not only borders, but lines.
The decisive power of the new century will be the states that can connect these two great geopolitical spaces to each other through corridors of trust, energy, technology and trade. For a pipeline has become as binding as a treaty, a port as deterrent as a division, a data cable as decisive as an alliance. The map of the twenty-first century is now read not in colours but in lines: which line passes through whom, where is it cut, in whose hands is it locked?
The Corridorland Index: the one who connects, versus the one who is passed over along that line, or can be run through, or can be operated!
A concept is poetry if it cannot be measured; if it can be measured, it is strategy. The real question that turns Corridorland from a slogan into an instrument of analysis is this: Is a state the subject of this space, or merely the ground that is passed over? Five criteria determine the difference between the two.
The first is multiplicity of connection. How many separate geographies, continents, seas, energy basins does a country join to one another with actual lines? To stand on a single route is to be the ground; to turn several routes into a junction is to be the subject. The second is irreplaceability. If this state is taken out of the circuit, does the flow stop, or is it easily routed around over another line? Real power lies not in being present, but in being impossible to bypass. The third is added value. Is the country merely the carrier of the line, or is it a node that processes, transforms and stores along it? It is not the place through which goods pass that wins, but the place where goods gain value. The fourth is the capacity for assurance. Can the state protect its own line militarily, politically and legally; and, beyond that, can it give others confidence that it can protect theirs too? The most expensive raw material of a corridor is trust; whoever cannot produce it becomes a haulier, not an architect. The fifth is rule-making. Is it the party that sets the standards, tariffs and transit regime of the line, or the party that complies with a rule set by someone else? He who sets the rule governs; he who follows the rule merely uses.
These five criteria also remind us that Corridorland is not a geopolitical determinism. Geography offers a possibility, not an outcome. To stand at the junction is as much a risk as it is an advantage: the line that connects the most is the line that stops the most when it is cut; to be a hub is at the same time to be a target. For this reason Corridorland is as much a declaration of responsibility as a promise of power. What makes a state its subject is not geography itself, but the ability to turn that geography into will, institution and continuity.
The silent race of the age of corridors
Let us not take this picture for a theory hanging in the air. Corridorland has long since begun to be built; and by more than one hand at that. China, with the Belt and Road Initiative, is weaving a gigantic network of connections stretching from the Pacific to Europe; for it every port is a position, every railway a strategic artery. India is drawing its own axis with the IMEC line, which promises to connect the Gulf and Europe. Russia and Iran are seeking, with the North-South corridor, a new route that goes around the embargoes. Europe, meanwhile, is trying to make up for its lateness with the Global Gateway.
In other words, the great struggle of the twenty-first century is being waged not on front lines but on route lines. Whose map cuts across whose map, whose node locks whose node? In this silent race some countries content themselves with being the ground over which corridors pass; others choose to be the subject that builds, manages and secures the corridor. The difference is the difference between standing at the edge of history and standing at its centre.
The Development Road, the Middle Corridor, the energy-line and grain-diplomacy initiatives that Türkiye has been talking about in recent years are the traces of precisely this awareness. The agreement signed in Mecca, too, stands not outside this context but right in the middle of it. To regard it as nothing more than a security text would be to see only a single piece on the chessboard and not the game.
That is exactly why reading the agreement signed in Mecca solely as a security document will fall short. This agreement can also be assessed as the sign of a search for a broader strategic integration between the production capacity of Eurasia, the energy transition of the Gulf and the maritime trade of the Indian Ocean.
Let us look carefully at the geography that brings the three countries together. Pakistan represents the gate opening onto the Indian Ocean and Central Asia’s dream of reaching the warm seas; the port of Gwadar is that dream made concrete. Saudi Arabia is an energy giant reinventing itself for the post-oil world; it now wishes to be the country not only of crude oil, but of the sun, of green hydrogen and of gigantic infrastructure visions. Türkiye, for its part, stands on the threshold that can connect one of these two ends to Europe and the other to the Caucasus and Turkestan. What emerges when the three come together is not the sum of three armies; it is the possibility that three geographical functions, ‘the gate, the source and the bridge’, may unite along a single line.
If this security foundation can be supported by transport corridors, green hydrogen investments, digital infrastructures, joint industrial zones and scientific cooperation, what emerges may be not merely a new defence architecture, but a new geoeconomic axis. Security here is not the ultimate aim; it is the ground. Just like the foundation of a building: nobody lives in the foundation, but without the foundation no storey rises. Joint defence lays the ground of trust on which an economy will be built.
What is built upon the security foundation?
The fate of an agreement becomes clear not on the day it is signed, but the following morning. Defence cooperation makes a promise; what makes that promise lasting are the bridges that rise upon it.
Imagine a green hydrogen line: energy produced from the sun of the Gulf feeds Türkiye’s industry and flows on to Europe’s carbon-free future. Imagine a transport corridor: a line along which cargo leaving Gwadar crosses the Persian Gulf and Anatolia and reaches the European market through Thrace. Imagine a digital backbone: an infrastructure that brings together the data centres, satellite capabilities and cyber defence of these three countries in a common architecture. Joint industrial zones, joint technology funds, joint basins of science… Each of these is, on its own, an investment decision; when they come together, they become a civilisational choice.
Türkiye at the Climate Summit: COP31 and its meaning:
This vision also has a climate dimension, which most often goes unnoticed. The age of oil was a geology; it was about what lay beneath whose soil. The energy transition, by contrast, is a geography; whose sun is more abundant, whose wind is stronger, whose line is closer to Europe’s carbon border. The desert of the Gulf was once solely the source of oil; tomorrow it may be the basin of green hydrogen and solar energy. This transformation will redraw the energy map and determine who on that map will be the carrier, who the producer and who the consumer. Climate diplomacy is therefore no longer an environmental matter, but a geopolitical matter of the first order. The road to a carbon-free future, just like oil, must pass through someone’s land and along someone’s line.
Of course, this picture is not a prophecy but a possibility. Corridors are at the same time fragility; the more a line carries, the more comes to a halt when it is cut. Different political cultures, different alliance obligations, regional rivalries and the shadow of the great powers are the real obstacles before this vision. Building a corridor has to do less with laying it than with protecting it; and less with protecting it than with convincing everyone that they gain from it. That is why the most valuable raw material of Corridorland is neither oil nor steel; it is trust. And trust is, in geopolitics, the resource that is hardest to produce and easiest to exhaust.
Türkiye’s changing role
It is exactly at this point that Türkiye’s role is changing. Türkiye is no longer merely NATO’s eastern flank. It is not merely Europe’s border country. Nor is it merely the neighbour of the Middle East.
Türkiye is one of the central countries that can connect the Black Sea, Turkestan, the Levant, the Gulf and the Indian Ocean to one another within the same strategic vision. Its privilege lies not in what it possesses, but in where it stands. However rich a country may be, it can remain on the margins; but to stand on a threshold is a power in its own right. Türkiye stands on exactly such a threshold: at the place where continents, seas, energy basins and lines of civilisation intersect.
Where, then, does Türkiye stand according to the five criteria we have just set out? In multiplicity of connection it is strong: it is one of the few countries where the Black Sea, Caucasus, Levant, Gulf and Eastern Mediterranean lines intersect. In irreplaceability it is indispensable on some lines and, on others, in a position that can be bypassed; the Straits make it unique, but not every route passes through the Straits. In added value it is advancing rapidly; it is now an industrial node where goods do not merely pass through but are assembled, processed and re-exported. Its capacity for assurance is perhaps its most distinct strength: with its defence industry, its unmanned systems and its deterrence, it is able to put a credible signature to the claim that it can protect its own line; the real meaning of the agreement in Mecca, too, lies here. Its weakest link, however, is rule-making: on most of the corridors it is still not the party that sets the rule but the party that adapts to the rule that has been set. The real leap that will carry Türkiye from ground to subject is hidden in precisely this fifth criterion.
Yet standing on the threshold is not an automatic superiority but a heavy test. Whoever is a bridge bears the load of both shores; and becomes party to the quarrel of both shores. To be a central country requires being able to talk to everyone, surrendering to no one, and connecting without becoming dependent. The real issue before Türkiye is to be able to turn this geographical destiny into a strategic will. For the place that the map bestows is turned into power only by vision, institution and continuity; the rest remains an unused privilege.
The great question of the future
For this reason the great question of the future is no longer “Heartland or Rimland?”. That was the question of the last century; and its answer, too, was given by the empires of the last century.
The real question is this: Who will be the architect of the new corridors to be built between the Heartland and the Rimland?
The agreement signed in Mecca does not give the answer to this question; but it puts the question on the table. And in history, asking the right question is at times worth more than many wrong answers. For those who found an age are those who first frame its question correctly.
The age of oil was hidden beneath the soil. The age of connections, however, is being built upon the lines. And in this age the winner will be not the one who possesses the most resources, but the one who can connect the most places to one another in the most reliable way.
The world sometimes changes with a war. Sometimes with a technology. But this time, perhaps, it will change with a new map opened by a single signature. On that map the borders still stand; yet destiny is now determined not by the lines, but by those who connect the lines to one another.
And among those who connect, there is a country standing on the threshold.
