What we are witnessing can be read as a global struggle for control, though not necessarily in the ideological language that defined earlier twentieth-century conflicts. The central issue is not only which political system appears more attractive. It is also who controls resources, finance, production, technology and the structures able to keep all of them moving.
For decades, Western power — especially the Anglo-American axis — rested on pillars that reinforced one another: the central role of the dollar, influence over financial institutions, leadership in strategic technologies, privileged industrial capacity and military power organized through alliances such as NATO.
That order has not disappeared. But it no longer operates in a world where Western relative advantage is as uncontested as it once was. China has built enormous industrial capacity, integrated supply chains, access to resources, infrastructure and a technological presence that forces the United States and its allies to compete differently.
A struggle over the rules
The transformation is visible in technology. ASPI's Critical Technology Tracker placed China, for 2019–2023, at the front of high-impact research in 57 of 64 critical technologies studied, with the United States leading seven. That does not mean China commercially controls 57 complete industries. It means the center of gravity in strategic research has shifted substantially.
This is why export controls, semiconductors, sanctions, industrial policy and supply-chain security have become central. The contest is not just over who sells more. It is over who can manufacture, who controls the critical stages, who has access to raw materials, and who can deny an adversary access to a technology.
When geography becomes power
A resource can exist and a factory can be ready, yet both still depend on routes. Oil, gas, minerals, components and goods must move. That makes a few straits and corridors disproportionately important.
Hormuz concentrates energy flows out of the Persian Gulf. Malacca links the Indian Ocean to the industrial economies of East Asia. Suez and Bab el-Mandeb connect Asia and Europe through the shorter route. Gibraltar links the Atlantic and the Mediterranean.
The U.S. Energy Information Administration estimated that in 2024 roughly 22.5 million barrels per day of oil and liquids moved through Malacca and about 20.7 million through Hormuz. UNCTAD estimated that around 22% of global seaborne container trade passed through Suez in 2023. The OECD estimated that roughly 19% of global maritime trade moved through Gibraltar that year.
The point is not to memorize every number. It is to understand the shape of the problem: when a large amount of activity depends on a narrow passage, a local disruption can become a crisis thousands of kilometers away.
China and the problem of dependence
China understands this architecture. Its industrial rise depends in part on energy, raw materials, maritime transport and market access. Hence the interest in diversifying corridors, investing in infrastructure, expanding naval capability, securing supply chains and reducing exposure to systems controlled by others.
The United States and its allies, meanwhile, have incentives to preserve advantages where they can still impose costs: advanced technology, financial access, alliances, military infrastructure, standards, intellectual property and logistics networks.
Reducing the entire field to a morality play about “good” and “bad” actors loses information. Great powers act inside incentives, fears, capacities and vulnerabilities. Understanding that field does not require approving their choices; it helps us read them.
Spain inside the map
For Spain, the transformation becomes concrete at the Strait of Gibraltar. Spain sits beside a major maritime artery and opposite a Morocco whose strategic weight has grown through relations with the United States, Israel, Europe and other actors.
Ceuta and Melilla add sovereignty, border, security, migration and cooperation. Spain needs Moroccan cooperation in some areas while also needing to prevent that need from becoming an incapacitating dependency.
The 2026 migration crisis in Ceuta showed how a localized pressure can become a national issue. There are documented facts — exceptional border pressure, humanitarian and security problems, intelligence warnings and political controversy — and there are more disputed interpretations about the degree of deliberate Moroccan involvement. Keeping those layers separate matters if we want to understand without converting hypothesis into fact.
The invisible map
When resources, factories, straits, financial systems, semiconductors, borders and alliances are viewed together, a recurring architecture appears: resource → route → chokepoint → dependence → alternative → sovereignty.
That pattern does not belong only to geopolitics. It appears in companies and personal lives. If all your income depends on one employer, there is a chokepoint. If an entire business depends on one platform, there is another. If critical knowledge lives only in one person's head, there is another.
The useful question becomes less “am I strong?” and more: what part of this system could stop everything else if it failed?

Score each point. This does not measure personal worth; it measures how much redundancy the system has today.
A way to carry it with you
Choose one real objective: housing, business, money, health, learning, mobility or communication. Draw only six elements: resource, route, chokepoint, dependence, alternative and control.
Then do not try to strengthen everything. Find the point whose improvement changes the whole system most. Sovereignty often appears not by accumulating more resources, but by building a second route.
