US Embassy websites

US Embassy website domain names generally look like countryname.usembassy.gov. That's good.

But some embassies have a second website. For example, we have mexico.usembassy.gov and we also have www.usembassy-mexico.gov.  Why??

Then we have US Mission websites. We have "missions" to the UN, EU, etc. These are generally assigned domain names like www.us.usmission.gov.  First, there's really no point in putting "us" in front of the mission name. It's already a US mission because it's under a US government TLD - .gov.  There should absolutely not be any other country's missions or embassy websites under our TLD. So they should just be un.usmission.gov and eu.usmission.gov, or spelled out like unitednations.usmission.gov and europeanunion.usmission.gov.
