Haha, as much as it should, this is not going to happen. The USA does what it wants and everyone else acquiesces or faces repercussions. ICANN may be "international", but remember where it's based.

Why? A TLD doesn't have to explicitly reference the country in which it's based. The big TLDs started in the US, so it shouldn't be a surprise that they're still under the US jurisdiction.

That said, fragmenting the internet into nationalistic TLD silos will probably have some negative consequences for the cross cultural nature of the internet, and it might help to give the non-obviously nation-based TLDs over to an international ruling body.

It's something to be weighed by the US govt. I hope they consider both sides carefully.

How would moving everyone to Colorado help?

.com is not a broken system, and .co.us is not as easy to type. Other than to strictly conform, I don't see any point in it.
