Do they need them to be good, or just to have a lot? Look at Hamas breaching the vaunted Iron Dome by sheer number of projectiles. Likewise, I heard Ukraine overwhelmed Russian S-300/400 with a simultaneous launch of something like a dozen ATACMS
ICBMs are notoriously difficult to intercept. Nobody realistically has an interception system able to take down enough of them to matter. The problem with old ICBMs is that they're less survivable if the enemy strikes you first so you need even more warheads and delivery systems to compensate.
