The ultimate end game if too many countries would pull at the unified single root that is the domain name system and ip address space, would be a split root. Different countries would resolve .com to different places, and packages going to one server will be going to an other, and people on one side will not be able to communicate with people on the other side since packages would no longer be globally routeable.

In concept, IANA and the group of global stakeholders could move the whole thing to a different country if US becomes too much trouble.
