As NATO and European officials emphasize Ukraine’s military as the primary security guarantee, technical discussions on peacekeeping contingent continue while Ukrainian strikes cripple Russian defense production
Summary of the Day — April 5, 2025
The shape of Europe’s future security architecture came into sharper focus today as NATO Secretary General Mark Rutte and European officials emphasized that a strong Ukrainian military—backed by Western security guarantees—remains the most effective deterrent against future Russian aggression. Technical discussions about a potential peacekeeping force continued in Kyiv, yielding “tangible details” according to President Zelensky. Meanwhile, Ukrainian forces struck two critical Russian defense industry facilities—the only plant in Russia producing fiber optic cables for military drones and a major explosives factory in Samara Oblast. On the battlefield, Russian forces gained ground near Toretsk and captured Solone near Pokrovsk, while Ukrainian forces made advances in the Kupyansk direction. Civilian casualties mounted as Russia launched 92 drones overnight, continuing its aerial campaign despite diplomatic overtures.

Strength Through Deterrence: NATO Emphasizes Ukrainian Military as Best Security Guarantee
NATO Secretary General Mark Rutte gave an interview to Ukrainian outlet New Voice on April 5, stating that the “first level” of security guarantees for Ukraine should be the Ukrainian military itself, which he called the “first line of defense in deterrence.” Rutte added that Ukraine’s European partners, including France, the United Kingdom, and Italy, are exploring additional security guarantees following any peace agreement.
The French General Staff similarly emphasized that Ukraine’s military is the country’s primary security guarantee for lasting peace. They added that France and the UK will work to develop “reassurance operations” to deter Russia from future aggression after implementation of a peace deal.
These statements underscore the growing consensus that Russia’s demands for Ukraine’s “demilitarization”—such that Ukraine would be unable to defend itself against future Russian aggression—run counter to the stated goal of achieving lasting peace in the region.
Peacekeeping Plans: European Delegations Meet with Zelensky on Security Forces
Delegations from the British and French general staffs met with President Volodymyr Zelensky and Ukrainian military leaders on April 4 and 5 in Kyiv to discuss how a future contingent of partner state forces could deploy to Ukraine. Zelensky reported that these meetings yielded “tangible details” about possible deployment, establishing Ukraine’s specific needs and identifying geographical vulnerabilities that may require support.
“There is tangible progress and initial details on how the partner security contingent might be deployed,” Zelensky said, thanking “the U.K. and France for their leadership” in bringing together countries open to deploying troops to Ukraine to monitor a potential ceasefire.
Key questions remain unresolved, including where forces would deploy, their specific responsibilities, and their authority to respond in case of a breach of a future peace agreement. Zelensky indicated that it might take a month or longer to finalize these details, with weekly meetings planned going forward.
NATO Secretary General Rutte suggested to Ukrainian media that while it’s best to wait until after a peace agreement to deploy peacekeepers, preparations should continue now so implementation can proceed quickly once peace is achieved.
Strategic Strikes: Ukrainian Forces Hit Critical Russian Defense Industry Facilities
Ukrainian forces launched significant strikes against two crucial facilities within Russia’s defense industrial complex on April 5, potentially hampering Moscow’s war machine.
Ukrainian Center for Countering Disinformation Head Lieutenant Andriy Kovalenko reported that Ukrainian drones struck the Fiber Optic Systems plant in Saransk, Republic of Mordovia—the only facility in Russia that manufactures optical fiber. The plant produces materials for control, communication, and data transmission systems, including drone control components for the Russian military. Geolocated footage showed explosions and fire in Saransk, though the Russian Ministry of Defense claimed to have shot down three drones over the region.
This strike is particularly significant as fiber optic cables are vital for Russian forces’ first-person view (FPV) drones, which have become increasingly important on the battlefield. The Fiber Optic Systems plant was the first and only plant manufacturing optical fiber in Russia, and its disruption could substantially impact Russia’s ability to supply troops with these advanced drone systems.
Separately, Ukrainian outlet Suspilne reported that Ukraine’s Security Service (SBU) conducted drone strikes against the Promsintez enterprise in Chapayevsk, Samara Oblast, causing at least 20 explosions and several fires. The SBU confirmed it was behind the strike, telling Kyiv Post that “SBU strike drones attacked the Promsintez plant in Chapayevsk, Samara Region,” which is “one of the leading manufacturers of industrial explosives (ammonal, ammonite, granulite) in the Russian Federation.”
The SBU source stated that the attack halted operations at the plant and emphasized that such objects are “absolutely legitimate military targets.” The Russian Ministry of Defense acknowledged the attack, claiming its forces destroyed six drones over Samara Oblast, while regional governor Vyacheslav Fedorishchev confirmed a drone strike against an industrial enterprise in Chapayevsk caused a fire.
Battlefield Developments: Russian Gains Near Toretsk as Ukrainians Advance Near Kupyansk
Fighting intensified across multiple fronts, with both sides achieving limited territorial gains in various sectors.
Ukrainian forces recently advanced south of Zapadne, north of Kupyansk, according to geolocated footage published on April 4. Meanwhile, Russian forces made gains in several areas, most notably capturing Solone southwest of Pokrovsk—a notable achievement in the ongoing battle for this strategically important city. Russian forces also advanced north of Druzhba, near Toretsk, and in northern Shevchenko southwest of Pokrovsk.
In Kursk Oblast, Russian forces advanced in northern Guyevo, south of Sudzha, while fighting continued near Oleshnya and Basivka. The General Staff of Ukraine reported that the “most intense situation is in Pokrovsk, Lyman, Toretsk and Kursk directions,” with sixty-five clashes reported near Pokrovsk alone in the past 24 hours.
According to Ukraine’s Armed Forces, Russia carried out 73 air strikes on April 5, dropping 106 guided bombs and using 844 kamikaze drones against Ukrainian positions and civilian infrastructure.
Aerial Assault: Russian Drone Campaign Continues Despite Ceasefire Talks
Russian forces launched a series of drone strikes against Ukraine on the night of April 4 to 5. The Ukrainian Air Force reported that Russian forces deployed 92 Shahed and decoy drones from Bryansk City, Millerovo in Rostov Oblast, Primorsko-Aktarsk in Krasnodar Krai, and occupied Cape Chauda in Crimea.
Ukrainian forces shot down 51 drones over northern, southern, eastern, and central Ukraine, while 31 decoy drones were neutralized, likely through electronic warfare interference. The attacks affected Sumy, Dnipropetrovsk, Kyiv, and Zhytomyr oblasts.
President Zelensky commented on the intensifying air campaign, stating: “The number of air attacks is increasing. The pressure on Russia is still insufficient, and the daily Russian strikes on Ukraine prove it.” He noted that over the past week, Russia has launched more than 1,460 guided aerial bombs, nearly 670 attack drones, and over 30 missiles of various types against Ukraine.
Governor Vitalii Kim reported late on April 5 that Russian Shahed drones had attacked the city of Mykolaiv, causing fires in two residential buildings. The attack occurred around 10 p.m. local time, with Russian kamikaze drones detected flying over several Ukrainian regions, including Kharkiv, Poltava, Sumy, and Chernihiv oblasts.
Technical Support: European Partners Bolster Ukraine’s Communication Infrastructure
France’s commercial satellite communications provider Eutelsat has been providing Ukraine with high-speed satellite internet service for approximately one year, funded by the German government, according to Eutelsat CEO Eva Berneke. While fewer than 1,000 terminals currently connect Ukraine to Eutelsat’s network, the company hopes to increase this number to between 5,000 and 10,000 “within weeks.”
Eutelsat spokesperson Joanna Darlington indicated that it remains unclear whether the European Union collectively or individual member states will fund additional Eutelsat efforts to support Ukraine. This technical support represents an important component of Western assistance, particularly as Ukraine’s communication infrastructure has been repeatedly targeted by Russian strikes throughout the conflict.
Diplomatic Divergence: US Embassy’s Response to Kryvyi Rih Attack Draws Criticism
President Zelensky expressed disappointment with the U.S. Embassy’s response to Russia’s attack on Kryvyi Rih the previous day, which killed 19 people, including nine children. U.S. Ambassador Bridget Brink had posted on social media: “Horrified that tonight a ballistic missile struck near a playground and restaurant in Kryvyi Rih. This is why the war must end.”

Zelensky found the statement “unpleasantly surprising,” writing: “Unfortunately, the response from the U.S. Embassy is surprisingly disappointing—such a strong country, such a strong people, and yet such a weak reaction. They are afraid to even say the word ‘Russian’ when speaking about the missile that murdered children.”
The president called for greater international pressure on Russia, adding: “We must pressure Russia—the one choosing to kill children instead of choosing a ceasefire.” This diplomatic friction comes as European leaders have more forcefully condemned the attack, with many in NATO trying to increase pressure on the Kremlin to sign the ceasefire agreement that Ukraine and the U.S. had previously accepted.
NATO Demands Answers: Alliance Presses Putin for Ceasefire Response
Following meetings in Brussels on April 3 and 4, NATO representatives demanded an immediate response from Russian President Vladimir Putin to the ceasefire deal that the U.S. and Ukraine have already agreed to.
“Today, Russia owes an answer to the U.S.,” said French Foreign Minister Jean-Noel Barrot. “It has to be yes, it has to be no—it has to be a quick answer.”
NATO Secretary General Mark Rutte added: “The ball clearly is in the court of the Russians. They are not moving fast enough, is my impression, including the impression I’m getting from my American interlocutors, that Russia really has to do more to bring this war to an end. The Ukrainians are really close to the American position.”
U.S. Secretary of State Marco Rubio reinforced this message following the NATO convention, stating: “The message is, the United States needs to know whether you’re serious or not about peace. Ultimately, Putin will have to make that decision.”
Ceasefire Violations Continue: Russian Strikes on Energy Infrastructure
The Russian Ministry of Defense claimed on April 5 that Ukrainian forces conducted 14 drone and artillery strikes against Russian energy infrastructure in Bryansk, Belgorod, Smolensk, Lipetsk, and Voronezh oblasts and in occupied Luhansk and Kherson oblasts over April 4 and 5.
The Ukrainian General Staff countered these accusations, reporting that the Russian Ministry’s claims about Ukraine’s alleged violations of the temporary energy infrastructure ceasefire are false and that Ukrainian forces are only striking legitimate military targets.
This exchange highlights the ongoing confusion surrounding the partial ceasefire, which has yet to be fully implemented as negotiations continue. The Kremlin has blocked the partial ceasefire agreed to on March 25, insisting that the Black Sea truce would take effect only after some sanctions against Russia are lifted.
Macron’s Diplomatic Ascent: France Positions to Lead European Negotiations with Russia
French President Emmanuel Macron is reportedly positioning himself to become Europe’s point person in negotiations with Russian President Vladimir Putin, according to reporting by the Telegraph. France and the United Kingdom are the main players within the “coalition of the willing” that is developing plans for a peacekeeping force in a post-ceasefire Ukraine.
Sources within the French government indicated that Macron’s diplomatic rise comes as UK Prime Minister Keir Starmer has shown relative reticence. France maintains one of the few military operations in NATO that functions independently of the United States, primarily in former colonies in West Africa. It also operates an intelligence network separate from the U.S.-led Five Eyes, which proved valuable to Ukraine when the U.S. briefly cut off intelligence sharing at the beginning of March.
Macron has been one of the most vocal advocates for European rearmament, though unnamed officials suggested it was “apparently, not yet” the time for him to formally lead the coalition. The specific details of any peacekeeping commitment from the coalition, whether French or otherwise, remain vague as Ukraine awaits more concrete support.
Looking Forward: The Long Road to Security and Peace
As April 5 drew to a close, the outlines of potential European security arrangements in a post-war scenario became more defined, even as fighting continued across Ukraine. The emphasis on a strong Ukrainian military backed by Western guarantees signals a recognition that enduring peace will require effective deterrence—not just diplomatic agreements.
The reported Ukrainian strikes against Russian defense industry targets demonstrate Kyiv’s continued ability to reach deep into Russian territory to disrupt Moscow’s war machine. Meanwhile, Russian drone and missile attacks against Ukrainian civilian areas highlight the enormous challenges that remain in reaching a genuine ceasefire, let alone a lasting peace settlement.
Technical discussions about peacekeeping forces and security guarantees will continue in the coming weeks, offering a glimpse of what post-war security might look like. Yet the gulf between diplomatic conversations and battlefield reality remains vast, as both sides continue to jockey for position while the human cost of the conflict climbs ever higher.
