This is bureaucratic inertia. It starts with Reagan's SDI program, repackaged by each of the Bush's. It's like a booger we just can't flick off. So they keep spending money without any real idea of how it fits into a deterrence policy. It isn't going to alter the strategy of an all out attack by China. And it won't alter the outcome. It's nonsensical to consider this worth the money without protecting specific targets. It's not good enough to just randomly save a few cities. If this is about DPRK, it's an announcement in advance that your diplomatic strategy has a decent chance of failing. If this is about giving a president defensive options, it's not going to do that because they will just say "these are really bad odds" and go for a preventative/preemptive strike instead. They know that too so you've just invited your adversary into a surprise first attack scenario as possibly their best chance. It's a nonsense program, and even more ridiculous to tweet about it.
