Can Europe arm Ukraine—or even itself?

Nothing shows the problem more starkly than artillery shells. At the height of Ukraine’s summer counter-offensive, it was using some 7,000 a day, significantly more than the Russians. This has reversed: since last month, while Ukrainian forces have been rationed to 2,000 shells a day, the Russians have been firing five times that number. Talk of a stalemate is complacent. The West now faces a choice, said Jack Watling, an expert at RUSI, a think-tank in London, earlier this month. It can give Ukraine what it needs, “or cede an irrecoverable advantage to Russia”.
