If Ukraine is to have any chance, it needs arms. Part of the reason that it's not getting these faster is a sort of reluctance on the part of its backers in the West because they're worried about escalation from Russia. But there's another reason as well, which is, I think, even more worrying, which is that the defense industries of the West are really not equipped for the strategic realities of the 21st century. In a way, this war is a wake-up call for weapons procurement in the West.
