The Institute for the Study of War (ISW) reports that Russia is unlikely to engage in genuine negotiations with Ukraine due to Ukraine’s critical shortage of Patriot missile interceptors. This deficiency allows Russia to believe it can achieve its objectives militarily. Ukraine’s air defenses are increasingly vulnerable, now facing newly produced Russian weaponry rather than older stockpiles. This escalation in the quality of incoming attacks, combined with limited interceptors, poses a significant threat to Ukraine’s defensive capabilities. The ISW assessment suggests Russia views Ukraine’s weakening position as reinforcing its strategy of attrition. Consequently, Russia sees no compelling reason to compromise at the negotiating table while maintaining a perceived military advantage. This situation highlights the urgent need for continued and increased Western support for Ukraine’s air defense systems.
