Defense Briefing

Ukraine has hit multiple targets in Moscow, destroying a Russian Su-57 stealth fighter 1,700 km behind the front line – the deepest confirmed strike of the entire war. The escalation follows mutual ceasefire announcements that apparently did not hold. Polymarket rates a ceasefire by end of 2026 at only 26% probability.

According to ISW, Russia lost a net 116 square kilometers in April 2026 – the worst month on the battlefield since the war began. Ukrainian drones systematically strike Russian air defense, radar systems, and logistics hubs up to 170 km behind the front. The strategic initiative appears to be shifting in favor of Kyiv, which will significantly impact ceasefire negotiations.

In light of threatened US troop reductions, European governments are for the first time seriously discussing the activation of Article 42.7 of the EU Lisbon Treaty as a collective defense guarantee outside NATO. NATO Secretary General Kallas emphasized at the EPC summit in Yerevan that American troops also protect US interests. CEPA and GMF are calling for three structural reforms to operationalize the European defense pillar.

The US agency CISA has officially instructed critical organizations to prepare for cyberattacks, as military planners expect targeted strikes on economically relevant systems in every modern geopolitical crisis. Since the US-Iran conflict beginning in February 2026, Iran-affiliated APT groups have shifted to more destructive attacks against OT/ICS systems in energy, water, and municipal administration – a qualitatively new level of escalation. Stryker Corporation suffered a far-reaching attack in March 2026, which serves as a warning signal for the industrial sector.

North Korea officially inaugurated a Memorial Museum on April 26, 2026, for soldiers killed in the Ukraine war – unprecedented public evidence of Pyongyang's direct military participation on the Russian side. Simultaneously in Yakutsk, a monument for fighters from the Ukraine war was erected on the grounds of a demolished memorial to Polish victims of Soviet repression. The open institutionalization of North Korean war participation significantly changes the geopolitical dimension of the conflict and is likely to reignite Western sanctions debates.
