> emails containing classified information

It's incredibly embarrassing if they're not using any kind of encryption for this.

Why is classified info allowed on an internet connected computer in the first place?

Well maybe the USA shouldn't get those top level TLDs? (Eg .gov or .mil or .edu). What's wrong with them having to use a second level domain like ".us.gov"?

It's been this way for 40 years. Are you a taxpayer? I'd rather not pay for any such retrofit. Furthermore, what makes you think that typos won't be made with any different domain name? Why would a fake hypothetical improvement of the situation drive a massive rewrite of millions of lines of code, server configurations, TLS certificates, specification documents...?

You're vastly exaggerating the costs of changing domains (and setting up a redirect).

I'm glad you mention TLS certificate, because those are an ongoing thing, not something you set up once leave unchanged for 40 years.

You can't set up a redirect, because if you leave a redirect in place, then people can send email to the original domain, and we're back where we started with the Mali misdirections. That's what the article is about.

True, but to avoid chaos you have a redirect for a while. Send a warning at first, then send an error.

This is the US Military we're talking about. Have you ever tried to enter an Air Force base without ID and clearance?

You know what comes after a warning.

I'm pretty sure the GP's point was that the US shouldn't have .gov/.mil etc, every country essentially has a form of government and military — And besides .gov.us would be more explicit.

Inventors' privilege.

The USA gets those top level TLDs because that's who created the Internet in the first place. It's an outgrowth of a US military project called ARPANET.
