Absolutement.
More authoritative sources would be great  in fact dbpedia may be as good as it gets, as it often is (at least for the moment).

As far as sameAs .org is concerned, I only (aim to, but sometimes I fail) include URIs that resolve to RDF.
And of course, often need others to have done the hard work of establishing the link.
So even for the excellent http://www.fao.org/countryprofiles/geoinfo.asp there are (as far as I can see) no resolvable URIs, nor any sameAs links.

The actual problem, as is well shown by your sameas.org <http://sameas.org>  example, is not the lack of URIs for countries, but to figure out which are "cool" (stable, authoritative, published following best practices). sameas.org <http://sameas.org>  yields 23 URIs for Austria, 29 for France etc.
Supposing they are all really "equivalent" in the strong owl:sameAs sense, any of those should do, but ...
On the other hand, maybe more authoritative sources are absent of the sameas.org <http://sameas.org>  list, such as the excellent FAO ontology pointed by Dan. And above all, which is definitely missing are sets of URIs published by ISO itself.
There is an ongoing work aiming at authoritative URIs for ISO 639-2 languages by its registration authority at Library of Congress. http://www.loc.gov/standards/iso639-2/. As I understand, those URI will be published under http://id.loc.gov/authorities/, so watch this space. I cc Rebecca Guenther who is in charge of this effort at LoC, she'll certainly be able to provide update about this, and maybe she's aware of some equivalent effort for ISO 3166-1. But according to an exchange I had with her a while ago, ISO itself might be "years away" from publication under its own namespace, unfortunately.

There are quite a few, but I don't know which other ones follow ISO 3166-1.
http://sameas.org/?uri=http://dbpedia.org/resource/Austria
Gives a selection.
Or also
http://unlocode.rkbexplorer.com/id/AT
http://ontologi.es/place/AT

Our site, http://unlocode.rkbexplorer.com/id/AT
is our capture of UN/LOCODE 2009-1, the United Nations Code for Trade and
Transport Locations, which uses the 2-letter country codes from ISO 3166-1,
as well as the 1-3 letter subdivision codes of ISO 3166-2
See http://www.unece.org/cefact/locode/
It also gives inclusion and coords, etc.
We need to do more coref to other than onologi.es <http://onologi.es>  .
