The Week the War Came to Moscow: Escalation, Deterrence, and the Fracturing of European Security

In the early hours of Monday, May 5, a Ukrainian drone slammed into an upscale residential high-rise in south-western Moscow, less than ten kilometres from the Kremlin. It was the third consecutive night that the Russian capital had come under drone attack, and it underscored a reality that the Kremlin has been reluctant to acknowledge publicly: after more than four years of full-scale war, the conflict is no longer confined to Ukrainian territory. The strike shattered windows and left debris scattered across the street below. Mayor Sergei Sobyanin confirmed that two additional drones were intercepted, while Vnukovo and Domodedovo international airports suspended operations overnight. The Russian defence ministry reported that 117 drones were intercepted across several regions, with 60 alone targeted at the St Petersburg area in what regional governor Aleksandr Drodzhenko described as a "massive" attack.

The timing was no coincidence. In fewer than four days, Russia will hold its annual Victory Day parade on Red Square, the centrepiece of the country's commemoration of the Soviet defeat of Nazi Germany. Yet this year's parade has been dramatically scaled back. For the first time since Vladimir Putin revived the Soviet tradition of parading heavy military hardware through the capital in 2008, there will be no armoured columns rolling past the Kremlin walls. The Russian defence ministry confirmed that cadets from Suvorov and Nakhimov military schools will not participate, nor will any column of military equipment. Kremlin spokesman Dmitry Peskov attributed the reductions to a "terrorist threat" from Ukraine, insisting that all measures were being taken to minimise danger. The admission is extraordinary: Russia's most important patriotic ritual has been hollowed out by the very war it was meant to celebrate.

Mobile internet restrictions have been imposed across Moscow for much of the week, with telecoms operators citing security reasons. Pro-Kremlin military bloggers had speculated for weeks about the growing vulnerability of the parade to Ukrainian long-range strikes. As one prominent blogger, Ilya Tumanov, put it: imagine the parade standing at attention while a missile threat is announced. The propaganda blow alone would be significant, regardless of whether anything actually struck. The symbolism cuts deep. Victory Day remains, in the assessment of most Russian and foreign analysts, the primary historical narrative that binds the country together. To see it curtailed is to watch the war erode the very foundations of the state's legitimacy at home.

Meanwhile, the broader strategic picture is shifting in ways that few anticipated even six months ago. Ukraine launched a missile and drone attack overnight on May 5 that reportedly struck a critical military-industrial site in Cheboksary, the capital of the Chuvash Republic, roughly 650 kilometres east of Moscow. The strike, reported by Russian Telegram channels, represents a remarkable expansion of Ukraine's reach into Russia's industrial heartland. Ukrainian forces have also struck three Russian oil tankers, a cruise-missile carrier warship, and a patrol boat in separate attacks on two Russian ports, according to President Volodymyr Zelensky. These were vessels belonging to Russia's so-called shadow fleet, used to circumvent Western sanctions on oil exports.

The economic dimensions of this escalation are significant. According to data cited by Zelensky, Russian crude oil revenues surged to 2.3 times their December-February levels during the third week of the Iran war, as Middle Eastern supply disruptions pushed prices higher and the United States renewed a waiver allowing countries to purchase sanctioned Russian oil. Yet in the fourth week, Ukrainian drone strikes on Russian energy infrastructure wiped out approximately one billion dollars in earnings, eradicating roughly two-thirds of the previous week's gains. Ukraine has clearly learned from observing the Iran conflict's impact on global energy markets, and is now applying those lessons with devastating precision against Russia's own oil infrastructure. Strikes on the Tuapse refinery in southern Russia caused a major oil spill and residents reported black rain falling across the city. Near Perm in the Urals, some 1,500 kilometres from the Ukrainian border, clouds of smoke rose after a drone struck an oil pumping station.

Simultaneously, Ukraine has been conducting a remarkable diplomatic campaign to convert its battlefield expertise in drone warfare into international partnerships. Zelensky has visited Saudi Arabia twice in recent months, signing defence cooperation agreements with the Gulf states that are themselves under threat from Iranian missiles and drones. Ukraine has concluded deals with Saudi Arabia, the UAE, and Qatar to share drone technology and expertise. It signed a substantial defence cooperation agreement with Norway worth $8.6 billion as part of a $28 billion support package extending to 2030, and another with Germany valued at $4.7 billion covering drones, missiles, software, and modern defence systems. The EU-backed loan of 90 billion euros, long blocked by Hungary's former prime minister Viktor Orban, was finally released after his electoral defeat last month, providing Kyiv with the financial runway it desperately needed.

Yet for all of Ukraine's tactical ingenuity, the strategic environment remains deeply uncertain. The Pentagon's decision to withdraw 5,000 troops from Germany, announced on May 2, has sent shockwaves through the NATO alliance. The chairs of both the Senate and House armed services committees, Roger Wicker and Mike Rogers, issued a joint statement warning that prematurely reducing America's forward presence in Europe risked "undermining deterrence and sending the wrong signal to Vladimir Putin." They argued that the forces should instead be redeployed eastward rather than withdrawn from the continent entirely. President Trump went further, telling reporters that the United States would be "cutting way down, and we're cutting a lot further than 5,000." The US currently maintains more than 36,000 active duty troops in Germany, its largest deployment in Europe by a wide margin.

The withdrawal is partly the product of a diplomatic spat between Trump and German Chancellor Friedrich Merz, who had remarked that the United States was being "humiliated" by Iranian negotiators and lacked a coherent strategy. Trump responded via Truth Social, and the troop announcement followed within days from Defence Secretary Pete Hegseth. German Defence Minister Boris Pistorius stressed that the American presence remained in both countries' interest, while NATO Secretary General Mark Rutte acknowledged that the alliance had "heard" Washington's frustrations. At the European Political Community summit in Yerevan, Armenia, on May 5, French President Emmanuel Macron described American indifference to European security as "the elephant in the room," while British Prime Minister Keir Starmer admitted that alliances "are not where we want them to be."

The parallel expulsion of three Russian diplomats from Austria on May 4 adds yet another dimension to this unfolding crisis. Austrian Foreign Minister Beate Meinl-Reisinger accused the diplomats of operating a "forest of antennas" on the roofs of diplomatic buildings in Vienna, used to intercept satellite communications. Austria's domestic intelligence service had long regarded these installations as a thorn in its side, and the country's own constitutional protection report described Vienna as "one of the last remaining locations for Russian signals intelligence in Europe." Around 220 Russian diplomatic personnel remain accredited in Austria, and Moscow has vowed to respond harshly to what it termed "ill-considered actions."

President Zelensky announced on May 4 that Ukraine is proposing a unilateral ceasefire beginning at midnight on May 6, challenging Russia to reciprocate. The proposal stands in stark contrast to Russia's own declared ceasefire for May 8 and 9, which Zelensky dismissed as "not serious" given that Kyiv had received no official proposal and Russian attacks on Ukrainian cities have continued unabated. On May 4, a Russian missile strike on the town of Merefa in Kharkiv Oblast killed at least four people and wounded 18. Russia's overnight attacks on Ukrainian energy infrastructure on the night of May 4-5 killed five and injured 37, according to Ukraine's gas utility. Since the beginning of 2026, Russia has launched over 800 drones against Ukraine's port infrastructure alone.

The convergence of these developments — the sustained drone campaign reaching deep into Russia, the erosion of Moscow's most important patriotic spectacle, the fracturing of the transatlantic security relationship, and the intensification of espionage countermeasures in central Europe — points to a war entering a volatile new phase. Both sides are reaching further and hitting harder, while the diplomatic architecture designed to contain such conflicts is showing signs of unprecedented strain. As Zelensky warned at the Yerevan summit: "This summer will be a moment when Vladimir Putin decides what to do next. We must push him towards diplomacy." Whether the combined weight of military pressure and economic pain will be sufficient to do so remains the defining question of the conflict.
