No, they have not. Each country can manage country-code top level donains, but that's just it: a specific top-level domain they are free to use. That doesn't negate them the right of using other domains, just like if you buy a domain name you don't lose the right of using a second or a third one.
It boggles the mind how anyone in their right mind can believe that a cyber-squatter shoud somehow have the right to hold the domain name of a sovereign nation for ransom.
