Especially since the announcement provides no information about how the DoD or DHS will be evaluating what to approve, and it's unlikely that they have the resources to do any meaningful security evaluation on that many products.

The DOH and DOW have a lot of resources. And I would guess the DOW has a lot of intelligence resources and most likely the DOH also I mean it is their job to keep the homeland safe. But I would agree. It probably will involve a lot of marshaling of those resources and reorganization. But who's to say they haven't done that already. My general point is that the conversation in this thread completely ignores that this is an imposition of a different regulatory scheme, not a banning. And actually it's in favor of enforcing more security on routers which everybody has been screaming for for years.
