If you would like to understand the arguments they're out there. Arms Control Wonk blog and podcast. My personal view is that we should build them to shield from states like the DPRK, but the contrasting view is that it destabilizes Mutually Assured Destruction. We don't know how many of their missiles we'll be able to intercept in the event of a mass strike, so it could make our leaders overly confident to take actions that would escalate. That's the critique, and I think it has some merit, but I also think that there are people that I admire, like Jeffery Lewis, that hold that view or something similar to it. For whatever it is worth, I've personally worked on arms control and in intelligence, so this opinion is not coming out of the blue.
