Here’s what’s happening in geopolitics today. Today’s edition begins in New York, where Trump found common ground with Mayor Zohran Mamdani before turning to an Arctic security deal with Denmark and Greenland.
Elsewhere, Pope Leo heads to France amid demands for greater accountability over clerical abuse, South Sudan clears a path towards its first post-independence election, and China installs a new political chief in Tibet.
If you thought tanks were done and dusted, think again… Today we bring up a new case study that shows tanks may finally be entering a new phase.
Donald Trump met New York City Mayor Zohran Mamdani at Gracie Mansion on Monday during his visit for the UN General Assembly. Their wide-ranging discussion covered affordable housing, immigration and public safety, with Mamdani seeking federal support for a proposed redevelopment of Sunnyside Yards in Queens. No funding commitment was announced, but both leaders pledged continued cooperation despite their political differences.
Trump is due to sign a security agreement with Danish Prime Minister Mette Frederiksen and Greenlandic Prime Minister Jens-Frederik Nielsen at the UN General Assembly in New York. The deal would expand the American military presence in Greenland by reopening facilities at Narsarsuaq and Mestersvig, while placing broader responsibility for Arctic security under NATO. Denmark and Greenland say the agreement preserves Danish sovereignty and Greenlandic autonomy, potentially ending months of tension caused by Trump’s earlier push to acquire the strategically important island.
Pope Leo XIV will begin a four-day visit to France on Friday, the first formal papal trip to the country in nearly two decades. In Lourdes, he is scheduled to meet privately with seven survivors of clerical abuse as the French Church continues to confront a 2021 independent inquiry estimating that approximately 330,000 children were abused in Catholic institutions between 1950 and 2020. The Pope will also visit Paris and Metz, meeting President Emmanuel Macron and addressing issues including European unity, peace and the ethical development of artificial intelligence.
South Sudanese President Salva Kiir has signed amendments removing legal requirements for a permanent constitution and national census to be completed before elections can take place. The changes clear a major procedural obstacle ahead of the vote scheduled for 22 December, which would be the country’s first national election since independence in 2011. The main opposition coalition has rejected the amendments, while concerns persist over electoral preparations, political tensions and whether the vote can be conducted safely and inclusively.
China has appointed Hu Changsheng as Communist Party secretary of Tibet, making him the region’s highest-ranking political official, state news agency Xinhua reported. Hu previously served as party chief of the northwestern province of Gansu and has also held senior positions in Heilongjiang and Fujian. He replaces Wang Junzheng, who had led Tibet since 2021, although Beijing did not immediately announce Wang’s next role.
Russia-Ukraine The Return Of The Tank? Is one of man’s most beautiful yet equally terrifying creations seeing the comeback it deserves after years of unnecessary slander? It very well may be, there have been growing hints about this since the beginning of the year. We have so far discussed Ukrainian mechanised counterattacks using drones in combined operations first on the Pokrovsk’e front, we then saw the Russian mechanised assault at Maiak and now we’re getting more information about the drone-tank combined operations around the Ukrainian counteroffensive’s north of Lyman.
The key to the counteroffensive was Ukraine’s combined arms effort – Kirichenko Ukraine’s counteroffensive on the Lyman front has demonstrated that tanks and mechanised forces retain a role despite the growing dominance of drones. Conducted over several months under operational secrecy, the Third Army Corps’ Operation Vivaldi combined pressure on Russian rear areas with ground attacks, reducing a salient threatening the northern approaches to Ukraine’s Donbas defensive belt.
The operation’s significance lies in how these capabilities were coordinated. Strikes against Russian logistics weakened forward positions, while electronic warfare, drone support and mechanised assaults helped Ukrainian troops exploit emerging opportunities. This suggests improvements in Ukraine’s ability to conduct combined-arms operations following the difficulties experienced during its 2023 counteroffensive.
However, Lyman does not demonstrate that armour can operate freely across the battlefield. Ukrainian soldiers interviewed by CEPA described tanks as increasingly scarce in some sectors, where persistent surveillance and strike drones make movement and concealment difficult. Protective structures, electronic warfare and coordination remain essential to their employment.
The challenge is sustaining an advance. Forces moving beyond their initial objectives remain exposed to artillery and drones, while lengthening supply routes creates additional vulnerabilities. Lyman therefore offers evidence that mechanised manoeuvre remains possible under favourable conditions, although turning local gains into a sustained operational breakthrough remains difficult.
Russia’s deployment of Arena-M active protection illustrates how armies are trying to restore the survivability of tanks on a battlefield dominated by drones. The system uses defensive countermunitions to intercept incoming threats and has been adapted to engage first-person-view attack drones.
If you remember back in July was when we saw the first notable example emerging during a mechanised assault around Maiak utilizing the Arena-M, in the Dobropillya direction. Ukrainian veteran and drone specialist Dmytro Putiata reported that one tank intercepted seven FPV drones, while destroying a tank required between 15 and 20 drones during the engagement. I will note that these figures remain attributed battlefield accounts rather than independently verified measures of the system’s average effectiveness.
Nevertheless, the implications are significant. Even without making tanks invulnerable, active protection can increase the ammunition, time and coordination required to destroy them, potentially allowing crews greater opportunity to complete their missions. However, Arena-M-equipped tanks were still lost. The biggest drawback is its finite ammunition, meaning that the tanks defense is finite, leaving vehicles vulnerable once countermunitions are exhausted.
The broader lesson is that improved protection can support a recovery in armoured manoeuvre, but cannot achieve it alone. Tanks still require coordinated infantry, reconnaissance, electronic warfare and fire support to operate effectively under pressure.
Both sides are looking to break the tactical deadlock anyway they can. As the tank surplus continues to grow, at least for Russia, both sides are seeing this as a tool not being utilised. So far, the main focus point in the short term is to lengthen the operating room for tanks to engage enemies and participate in missions. In the long term, it will be to neutralise the enemies ability to launch drones whilst saturating the airspace with friendlies, creating a cover for mechanised assaults.

TODAY IN HISTORY (Sep 22, 1980): Solidarity formed
Solidarity, the Polish trade union and political party that became a hotbed of resistance to Soviet control, was founded this day in 1980 when delegates of 36 unions met and united under the leadership of Lech Wałęsa.

Yes, more evidence that the tank is still appreciated on the modern battlefield. Recent footage shows a pair of turtle tanks conducting a mission under the cover of drones.

Renewed war in northern Ethiopia is reshaping regional alliances, threatening stability across the Horn of Africa and potentially complicating external support for Sudan’s RSF.
