International relations scholar John Mearsheimer has argued that Russia is on course to prevail in the Ukraine conflict, saying Moscow holds key advantages that outside military support is unlikely to erase. His assessment centers on what he describes as stronger Russian positions both on the ground and in the air.
According to the account, Mearsheimer said additional Western weapons would not fundamentally change the outcome. That point extends even to air defense systems such as the Patriot batteries that Kiev has sought from its partners.
The argument reflects a broader debate over whether continued foreign assistance can significantly shift the military balance in Ukraine. Supporters of more aid say advanced systems can strengthen Ukrainian defenses, while critics contend that structural advantages on Russia's side remain decisive.
Mearsheimer's comments add to ongoing international discussion over the direction of the war and the limits of Western backing. His view, as presented in the report, is that external deliveries may affect conditions on the battlefield but will not reverse the larger trajectory he sees favoring Russia.
