Yemen, Iceland, Sahel: the fault lines of a world under tension

Accroche

In a single day, 73 civilians were injured by Houthi strikes on cities and economic infrastructure in southern Saudi Arabia, while Yemeni loyalist forces attempted to retake Sanaa. The same day, Iceland summoned the American ambassador after Donald Trump published a map showing the island under the American flag. Two events, two theaters, one logic: power rivalries are now unfolding on all fronts, including symbolic ones.

Key Points

1. Yemen, a laboratory for a proxy conflict that is bogging down. Loyalist forces launched a counter-offensive to retake Sanaa, the capital that fell to the Houthis in 2014. Houthi strikes hit civilian areas, injuring 73 people in one day. Riyadh warned against the continuation of these attacks, highlighting the escalation of regional tensions. This sequence illustrates the inability of international mediations to impose a lasting ceasefire, while the conflict has already displaced more than 4 million people according to available institutional data.

2. Iceland summons the American ambassador: a weak but revealing signal. Donald Trump's publication of a map showing Iceland as part of the "United States of America" provoked an immediate diplomatic reaction. The Icelandic Ministry of Foreign Affairs described the message as "entirely inappropriate." This incident comes against a backdrop of past tensions concerning Trump's intention to acquire Greenland and concerns in Europe about the reliability of the United States. Beyond the provocation, this sequence reminds us that small European powers must navigate between security dependence on NATO and the preservation of their sovereignty in the face of unpredictable American initiatives.

3. The United Kingdom bets £100 million on Ukrainian air defense. London announced an additional £100 million in funding to strengthen Kyiv's air defense capabilities before winter, including Patriot missiles and interceptors. This aid is part of a broader NATO program, the Prioritised Ukraine Requirements List (PURL), aimed at protecting Ukrainian civilian infrastructure and armed forces from Russian attacks. At the same time, former Ukrainian officials speak of "serious attempts" to open negotiations between Kyiv and Moscow, without any concrete meeting being confirmed. Russian demands — limitation of the Ukrainian army and recognition of occupied territories — remain unchanged since February and are deemed unacceptable by Kyiv.

4. North Korea materializes its rapprochement with Russia. The inauguration of a road bridge to Russia, described by Pyongyang as a "concrete sign" of strengthening military and economic ties, formalizes an alliance that has intensified since 2022. This bridge is in addition to another under construction towards China, outlining a logistical architecture that bypasses international sanctions.

5. The Sahel under high tension: a "red alert" with divergent interpretations. Recent armed attacks and mutinies in Niger and Mali are interpreted by some regional sources as externally orchestrated destabilization attempts, with France as the spearhead, while other analyses point to internal fragilities. This divergence of interpretation fuels increased mistrust towards external powers and complicates any security cooperation.

Context

The current configuration extends dynamics initiated two decades ago: contested Western interventionism, the rise of revisionist powers, and the fragmentation of multilateral bodies. Yemen, at war since 2014, has become a theater where Iranian, Saudi, and Emirati interests clash. In Europe, the post-2022 period reactivated collective defense logics, but also tensions over the sovereignty of small states. In Africa, the wave of coups d'état since 2020 has reshuffled the cards, with a growing rejection of French influence in favor of new partners, particularly Russian ones.

Key Players

The United States is trying to maintain its Western leadership while managing multiple crises, from Ukraine to the Indo-Pacific. Its room for maneuver is constrained by internal polarization and contradictory priorities. Russia is consolidating its alliances with North Korea and Iran to compensate for its isolation, while China is extending its influence through infrastructure and economic partnerships. The European Union, fragmented, struggles to speak with one voice: the United Kingdom acts autonomously on Ukraine, Germany is shaken by the rise of the AfD, and Serbia is moving away from Brussels by honoring controversial figures. Regional powers — Turkey, Egypt, Saudi Arabia, Emirates — play their own part, as evidenced by the Greece-Egypt-Cyprus trilateral summit in El Alamein, convened by President al-Sissi to send a message to Turkey and its President Erdogan.

Data and Figures

Energy prices, although slightly down at the beginning of September 2026, remain high: Brent crude traded at $96.02 per barrel on September 1st, compared to $87.03 on August 31st, according to available public indicators. Henry Hub natural gas stabilized at $2.90 per million BTU, but jet fuel jumped from $4.02 to $4.19 per gallon in one day, a sign of persistent tensions in supply chains. In France, alerts on renewable production are multiplying: Corsican renewable electricity production fell by 43.21%, while renewable gas production in Burgundy increased by 45.59%, illustrating a multi-speed energy transition. These discrepancies reflect local vulnerabilities that weigh on European energy security.

Analysis of Stakes

In the short term, the multiplication of crisis hotspots — Yemen, Ukraine, Sahel — exhausts mediation capacities and increases the risk of accidental escalation. The British decision to sanction Israeli settlements, criticized by the American ambassador, shows that even historical allies diverge on sensitive issues. Energy markets remain nervous: any major disruption in the Middle East or the Red Sea would drive up prices, with global inflationary effects. In the medium term, the fragmentation of the international order favors ad hoc alliances and circumvention of sanctions, as illustrated by the North Korean bridge to Russia. The defense, logistics, and energy sectors are primarily concerned, but it is the credibility of multilateral institutions that is at stake.

Prospective Hypotheses

Scenario 1: Widespread Stalemate (probability 55%). Conflicts in Yemen and Ukraine continue, negotiations fail, and external powers continue to support their proxies. Indicators to monitor: intensification of Houthi strikes, new Western arms deliveries to Kyiv, absence of direct talks.

Scenario 2: Partial Diplomatic Breakthrough (probability 25%). Under economic pressure, Russia accepts exploratory discussions, while a local truce is established in Yemen. Conditions: credible mediation by China or Turkey, exhaustion of Russian military capabilities. Indicators: trilateral meetings, slowdown in fighting.

Scenario 3: Major Escalation (probability 20%). A naval incident in the Red Sea or an attack against a NATO country triggers a broader response. Conditions: miscalculation, unacknowledged attack against critical infrastructure. Indicators: aircraft carrier movements, terrorist alerts, sharp rise in oil prices.

Why it's important

These dynamics are not distant: they determine the price of energy you pay, the security of supply chains, and the stability of European borders. The convergence of crises — Yemen, Ukraine, Sahel, trade tensions — means that decisions made in the coming months will shape the global order for a decade. And what if the real fault line isn't between powers, but between those who suffer from conflicts and those who instrumentalize them?
