Western military aid has played a key role in Ukraine’s ability to preserve its independen- ce, but it is still insufficient to break Russia’s offensive potential, to recapture Russian-held territory, or even to stop Russia’s next possible offensives—in short, to end the war. Ukraine cannot rely on its own defence industry, a great part of which has been destroyed. For these reasons, it is necessary to increase both the scale and scope of Western military support for Ukraine, which should include more NATO-standard weapons than before.
