Here’s what’s happening in geopolitics today. Today’s edition opens with unexplained explosions at a Syrian army site near Aleppo, while Washington proposes an AI-era emergency hotline with Beijing.
Elsewhere, Taiwan’s labour minister makes a rare trip to China, Pakistani airstrikes deepen tensions with Afghanistan, and the US and Iran exchange fresh threats as Houthi attacks widen the regional conflict.
Trump allegedly paused potential strikes on the Houthi's over the weekend at the last moment, as European leaders unite in calls for preparation against Russia.
A powerful blast struck a Syrian army site near the town of Al-Eis in Aleppo province early Monday, triggering a series of continuing explosions and large flames visible from parts of the city. Emergency crews were initially unable to reach the facility, while authorities closed nearby roads, placed hospitals and ambulances on alert and advised residents to remain indoors. The cause remains under investigation, and officials have not yet reported any casualties or confirmed what was stored at the site.
US Treasury Secretary Scott Bessent has proposed creating a notification mechanism through which Washington and Beijing could alert one another to artificial-intelligence incidents carrying national-security risks. The proposal was raised during talks with Chinese Vice Premier He Lifeng in New York, where both sides agreed to continue a broader dialogue on AI safety and transparency. China has not publicly endorsed the mechanism, which could be considered by Presidents Donald Trump and Xi Jinping during their forthcoming summit in Washington.
Taiwanese Labour Minister Hung Sun-han travelled to Nanjing on Sunday for an APEC human-resources ministerial meeting, becoming the first cabinet-level official from President Lai Ching-te’s administration to visit mainland China. The meeting will address employment, vocational training, social security and the effects of artificial intelligence on labour markets, with no separate cross-strait talks announced. Taiwan participates in APEC as “Chinese Taipei,” while China is hosting this year’s meetings and a leaders’ summit scheduled for November in Shenzhen.
Pakistani fighter jets struck suspected militant hideouts in Afghanistan’s eastern Kunar and Paktika provinces on Monday, with Islamabad claiming that 28 militants were killed. Afghan authorities said the attacks instead killed three civilians and wounded four others, condemning them as a violation of the country’s sovereignty. Pakistan said the operation followed deadly attacks on its security forces and again accused Kabul of sheltering the Pakistani Taliban, an allegation Afghanistan’s Taliban government denies.
Donald Trump warned Iran that it faced further economic and military consequences unless it reached an agreement with Washington, while saying he remained open to meeting President Masoud Pezeshkian at the UN General Assembly. Iran’s military responded that any renewed attack would trigger sustained retaliation against US bases and interests, adding that regional countries assisting Washington would be treated as parties to the conflict. The exchange followed Houthi missile and drone attacks on Riyadh and Saudi energy infrastructure, widening a confrontation that has already disrupted shipping through the Strait of Hormuz and Bab el-Mandeb.
Geopolitics This is the year that keeps on giving, doesn’t it? The world seems to show no sign of slowing its march towards more disruption, conflict and agony. The past weekend brought another exhausting mix of genuine developments, alarming reports and speculation spreading faster than anyone could verify it. Was something big about to happen—or had something big already been called off?
Reports that Trump had cancelled planned strikes against the Houthis offered one possible explanation for the whirlwind. NYT reported that the president had pulled back from military action, while his early return from Camp David added to the anticipation surrounding Washington’s next move. The alleged reversal may be due to the fact that renewed American intervention could expose US shipping to retaliation and deepen the disruption around the Bab al-Mandab. At the current moment there is no threat, as a senior Houthi official told AP that American vessels would remain outside their targets under the existing ceasefire, while warning other countries against joining Saudi Arabia’s campaign. Washington therefore has something tangible to lose by entering the fight.I would also consider whether Trump sees Saudi dependence on American protection as negotiating leverage over Mohammed bin Salman. That is my interpretation, however, and tying it specifically to Saudi commitments on dollar-denominated oil sales would go further than the available evidence supports.
Meanwhile, Europe produced its own wave of anxiety. The warnings about Russian attacks felt increasingly urgent, but the sequence matters. Germany’s accusation over the attempted drone attack at Leipzig Airport, and the coordinated European statements that followed, came earlier this month. They formed the backdrop to the weekend’s unease, rather than all emerging at once. On September 1, Berlin blamed Russia for an attempted August 4 drone attack targeting a Ukrainian cargo aircraft at Leipzig Airport. Germany announced diplomatic measures, including the closure of Russia’s remaining consulate in Bonn. NATO, EU officials and national leaders issued closely aligned statements of support. That shared language helps explain why the messaging appeared unusually coordinated: governments were publicly demonstrating a common response to a specific incident.
More recently, Macron convened French political leaders on September 18 to discuss the growing hybrid threat. Concerns included railway disruption, a derailment in Normandy and fires near a military explosives site, although he avoided directly attributing those incidents to Russia. I have to be clear here, the distinction matters: events can warrant investigation and heightened security without their cause already being established. The wider concern is that pressure on Europe could take forms that remain difficult to attribute: sabotage, cyber disruption, interference with transport and threats against critical infrastructure. Such incidents create a difficult political calculation. Governments must decide what happened, who was responsible and how to respond, often while speculation has already reached its verdict online.
My reading is that these public warnings can serve several purposes simultaneously: preparing populations, encouraging stronger protection of infrastructure and signalling resolve to Moscow. Their timing deserves attention, but it does not establish that leaders have advance knowledge of an imminent major attack. With military developments, diplomatic signalling and social media amplification overlapping, it becomes remarkably easy to mistake a heightened state of concern for a countdown. And specifically to the people who are comparing this to early 2022, we had satellite imagery displaying significant Russian military movements that suggested an attack was going to be launched – at the moment we are simply not seeing that anywhere near the Baltics.
Indeed, it was a stressful weekend—and the uncertainty was a substantial part of what made it so.
