Russia's military campaign in Ukraine has stalled after four years of fighting, prompting Moscow to launch hundreds of drones and missiles in renewed attacks. The escalation comes as Russian forces struggle with battlefield losses and recruitment shortfalls, according to analysts tracking the conflict.

May marked the first month since Ukraine's 2023 counteroffensive where Russian forces lost more territory than they gained, despite a 37.5 percent increase in attacks. Western officials estimate nearly 500,000 Russian soldiers have died since the war began, with current monthly casualties reaching 15,000 to 20,000 troops.

To offset these losses, Russia has intensified coerced mobilization in occupied eastern regions, canceling student deferrals and using mandatory registration and raids. Meanwhile, Ukraine secured new European military support, including a $149 million arms package from Finland and 16 Gripen fighter jets from Sweden.

The shift reflects deteriorating Russian combat performance and growing Ukrainian confidence, analysts say. Moscow's desperate tactics suggest weakening battlefield position, potentially undermining future cease-fire negotiations as the Trump administration redirects focus toward Iran.
