Dutch Defence Minister Ruben Brekelmans said that the Netherlands is working to find ways to include President Zelenskyy in the NATO summit in The Hague. Unlike last year’s full participation, Zelenskyy may have a more limited involvement due to the lack of a Ukraine-NATO Council session. NATO plans to issue a shortened final statement at the upcoming Hague summit. The document may exclude references to Russia or Ukraine. In previous summits, Ukraine was a major topic. This is being done to avoid upsetting Trump.
Ukrainian intelligence official Oleh Ivashchenko reported that Belarus does have missile systems and jets capable of carrying nuclear weapons, but no actual nuclear warheads or Oreshnik ICBMs are currently in the country. He says infrastructure is still under construction, and deployment is unlikely anytime soon. This is in direct contradiction to claims made by both Belarus and Russia.
On May 27, the EU is set to formally approve a $170 billion SAFE common defense fund initiative to loan money to member states, European Free Trade Association countries, and Ukraine to quickly finance weapons procurement. Officials say the initiative could double arms supplies to Ukraine and dramatically improve the EU’s domestic arms production and security as the US wavers in its commitment to a peaceful and stable Europe. The SAFE program is part of the broader €650 billion ReArm Europe plan to ramp up defense spending across the continent.
Sweden will be allocating about $504 million to Ukraine to help fund its defense. About $10.5 million is going to the Demining Capability Coalition for demining equipment. $31.5 million is going to the Drone Coalition to help purchase various drones. The Maritime Capability Coalition will receive $5.2 million to fund training for Ukrainian Navy personnel no. $3.1 million is set aside for the IT Coalition to support Ukraine’s Delta management system. $105 million will be dedicated to “the Danish model” of arms procurement, where European countries buy equipment for Ukraine from Ukraine’s domestic arms industry. $43.9 million will be provided for armored vehicle equipment.

German Chancellor Friedrich Merz stated that Germany, France, the United Kingdom, and the United States have lifted all restrictions on Ukraine's use of long-range weapons for strikes inside Russia. Merz said Ukraine can now hit military targets in Russian territory. Many are taking this to imply that Germany is transferring Taurus missiles to Ukraine, but it could also mean that Germany has or is in the process of providing Ukraine with long-range strike drones or is assisting Ukraine in domestically producing its own long-range strike capabilities.
Kirill Dmitriev, head of Russia's sovereign wealth fund, expects several US companies to return to Russia in the second quarter of 2025. Dmitriev met with US Secretary of State Marco Rubio and other American officials in Saudi Arabia in February. He claims US companies lost $324 billion by leaving Russia after the 2022 invasion, with IT and media companies losing $123 billion, consumer and healthcare companies lost $94 billion, and finance companies lost $71 billion.
Ukraine's Foreign Intelligence Service says that Dmitriev is working to unfreeze Russia's $280 billion in frozen assets. Head of Foreign Intelligence Oleh Ivashchenko said that Dmitriev is trying to get the United States to focus on economic cooperation involving Arctic resources, oil, gas, and rare earth minerals rather than just the war and peace talks. This strategy aims to push the Ukrainian issue into the background and hope that the US forgets about the war in pursuit of Russian resources.

Germany is studying how to support the Ukrainian defense industry in producing long-range weapons. The topic is likely going to be discussed during Zelenskyy’s visit to Germany on May 28, at the invitation of Chancellor Friedrich Merz. Lithuania was the first country to fund long-range weapons for Ukraine, allocating €10 million in September 2024 for the Palianytsia missile drone.

Before the full-scale invasion, Ukraine had already allocated several hundred million hryvnias fort missile development, including the Sapsan AKA the Hrim-2. The program has produced two versions of the missile: a 900 mm diameter version with a 500 km range for domestic use, and a 600 mm version with a 280 km range for export. A successful test of Ukraine’s ballistic missile occurred on August 27, 2024. In April 2025, Minister Herman Smetanin said the production rate allowed for regular deployment of the ballistic missile and the long-range Neptune missile.
Germany’s Quantum-Systems has begun the production of Vector drone fuselages in Ukraine. Two Ukrainian facilities are producing all fuselage components and conducting R&D and maintenance. According to Dmytro Horlin, the Ukrainian-made fuselages are stronger and weigh approximately 250 grams less than the German-made versions. New payloads such as acoustic sensors, AI modules, 360-degree rotating cameras, and improved day and night optics are being tested.
The EU Temporary Protection Directive (TPD), introduced in March 2022 to support Ukrainians fleeing the war, is approaching the end of its lifespan. Originally, it was set to last until March 2025, but the European Commission later extended it to last until March 2026. Now, discussions are underway on whether to add one final year or phase out the program. Talks are expected at the No 12–13 June Justice and Home Affairs Council meeting.There may not be a legal way to extend the full program any longer, due to the way the TPD was originally written. There are currently talks underway to figure out how to gracefully deal with the program ending without causing gridlock in the refugee asylum systems of numerous countries.
