And you don’t even need them, for the short term. Virtually all of your DNS queries are answered by machines much closer to you than the root servers. If you don’t have it in a local DNS cache, you go to the authoritative nameserver for the domain you’re requesting, which is also not a root DNS server, but one of the millions of other zone nameservers. Shutting down the root servers can also be routed around by setting up a different configuration, or just routing the addresses for the roots to something else that you control.
Then you get to the backbones, which are a bigger deal. Shut a few of those down–maybe with the enforcement help of local cops and the FBI, assuming you can get them on board–and you’ll slow traffic to a crawl. No Netflix for most folks, not for a while. But communication itself would still find a way around.
And all of that assumes he can even get anyone to agree to this, and he’s probably the only person with any power who’s stupid enough to think this is a good idea. It just doesn’t work, not on any level, not even if he takes office, still thinks this is a good idea (which he doesn’t, this is an obvious bluff), and can find a bunch of idiots in power willing to help.
Root DNS servers are geographically spread and definitely not only in US.
