Greenland, Russian Sanctions, and Drones: Global Security Shifts into a New Era of Confrontation
Washington signs a security agreement with Denmark and Greenland, simultaneously adopting a sanctions law against Russia and Iran. These decisions, coupled with the escalation in Yemen and European alerts on drones, accelerate global geopolitical fragmentation.
Washington signed a security agreement with Denmark and Greenland on September 18, 2026, days after the adoption of a sanctions law against Russia and Iran. These two decisions, combined with the intensification of Saudi strikes in Yemen and the Latvian president's warning about drones, indicate a rapid recomposition of global strategic balances.
Key Points
1. Greenland: a “shared security” agreement that consecrates the projection of American power in the Arctic. The United States obtains “permanent control” over the island's security, according to official statements, while Copenhagen and Nuuk insist on the tripartite and shared nature of the agreement. This contradictory formulation masks a reality: the prohibition for any adversary – Russia and China first and foremost – from installing military bases or sensitive investments. The Arctic becomes a theater of direct confrontation.
2. Russian sanctions: the “Lindsey O. Graham Sanctioning Russia and Iran Act of 2026” considerably expands the American arsenal. The law targets Russian oil and gas revenues, authorizes customs tariffs on energy imports from Russia, and extends sanctions against Iran. It explicitly targets Chinese imports of Russian energy, creating direct leverage on Beijing days before Xi Jinping's visit to the White House.
3. Taiwan: Washington considers delaying arms sales until after the APEC and G20 summits. This decision, if confirmed, would constitute a temporary gesture of appeasement towards Beijing, but it exposes a strategic contradiction: the United States seeks both to sanction China for its purchases of Russian energy and not to exacerbate trade discussions.
4. Yemen: 26 Saudi strikes in 24 hours according to the Houthis, after attacks against Riyadh. The truce broken in July 2026 has given way to a military escalation that threatens maritime routes in the Red Sea and the Gulf of Aden. Shipping costs, already high, could increase further, affecting global trade volumes.
5. Europe: the Latvian president warns of a critical delay in air defense and drone warfare. Patriot missile stocks are insufficient, and NATO has not integrated the lessons from the war in Ukraine. This vulnerability is all the more concerning as Russia has launched parliamentary elections in the midst of war, strengthening the Kremlin's internal legitimacy.
Context
The Arctic has long been a space of scientific cooperation and strategic rivalry. Climate change has opened new maritime routes and facilitated access to resources. Threats of Greenland's annexation by Donald Trump in 2025 had created a major diplomatic crisis with Denmark. The September 2026 agreement is the outcome: a compromise that gives the United States security guarantees without a transfer of sovereignty. Meanwhile, the war in Ukraine has transformed sanctions into a primary economic weapon, and China has become an indispensable player in Russian energy supply chains.
Key Players
The United States, under President Donald Trump, pursues a strategy of maximum pressure on Russia and Iran, while seeking to temporarily stabilize relations with China. Denmark and Greenland obtain shared security guarantees but cede part of their strategic autonomy. Russia, which is organizing parliamentary elections in the midst of war, relies on the resilience of its war economy and Chinese support to circumvent sanctions. China, the largest importer of Russian oil and gas, is directly targeted by the new American law, complicating its position days before the summit with Trump. Saudi Arabia, engaged in a campaign of strikes in Yemen, seeks to weaken the Iran-backed Houthis. NATO, finally, faces a capacity deficit in air defense, as highlighted by the Latvian president.
Data and Figures
Energy prices illustrate the tensions. According to institutional data, Brent crude traded at $130.80 on September 15, 2026, compared to $107.02 for WTI. These high levels reflect geopolitical risks and disruptions to maritime routes. Henry Hub natural gas, at $2.97 per million BTU, remains moderate, but precious metal prices are reaching highs: gold at $4,378.80 per ounce, silver at $66.26, platinum at $1,800.40, and palladium at $1,297.47. These values indicate a demand for safe havens in the face of uncertainty. Base metals – copper at $0.4622 per ounce, aluminum at $0.1022, nickel at $0.5040, zinc at $0.1227, and lead at $0.0594 – show moderate pressure on industrial supply chains.
Analysis of Stakes
In the short term, the signing of the Greenland agreement and the sanctions law create a double shock. Energy markets are already incorporating a geopolitical risk premium, as evidenced by Brent above $130. Shipping companies, facing high transport costs and disrupted routes in the Red Sea, could pass these costs on to consumer prices. Industrial equipment sectors – turbines, compressors, pumps – indirectly benefit from increased investments in offshore exploration-production, according to market signals. In the medium term, the militarization of the Arctic and the strengthening of sanctions against Russia could accelerate the fragmentation of the global economy into blocs. China, targeted by US sanctions on Russian energy imports, could retaliate with restrictions on rare earths or trade measures. Europe, lagging in air defense, risks becoming a weak link in Western deterrence.
Prospective Hypotheses
Scenario 1 (probability 45%): Controlled escalation. The United States maintains pressure on Russia and Iran but delays arms sales to Taiwan to preserve dialogue with Beijing. China continues to buy Russian energy despite sanctions but avoids direct confrontation. Indicators to watch: the evolution of Chinese imports of Russian oil, Supreme Court decisions on tariffs, and troop movements in the Arctic.
Scenario 2 (probability 30%): Rupture. China, targeted by secondary sanctions, reduces its purchases of Russian energy under US pressure, which weakens the Russian economy and increases military tensions in Ukraine and Yemen. Saudi Arabia intensifies its strikes, further disrupting maritime routes. Indicators: Sino-Russian trade volumes, maritime freight prices, and military incidents in the Red Sea.
Scenario 3 (probability 25%): Partial détente. Xi Jinping's visit to the White House results in an informal agreement: the United States suspends certain secondary sanctions in exchange for a Chinese commitment not to support the Russian war effort. Denmark and Greenland obtain additional guarantees on their sovereignty. Indicators: joint statements after the summit, the evolution of arms sales to Taiwan, and Chinese investments in the Arctic.
Why it matters
These events are not mere diplomatic tremors. They redraw the lines of force of a world where energy, technology, and security are increasingly intertwined. For businesses, investors, and citizens, the consequences are concrete: more volatile energy prices, strained supply chains, and increased militarization of strategic spaces. The question is no longer whether fragmentation will occur, but how quickly it will set in – and who will pay the price. How is your organization preparing for a world where access to resources and maritime routes becomes a national security issue?
