I do not consider myself to be US-centric nor uneducated, but prior to the incident at the Winter Olympics in 2010 where a luge athlete from Georgia was killed during a training run, and here in Vancouver, the host city for the Olympics that year, this incident was pretty major news. I had no idea previously that there was evidently a country that was also called Georgia, although I had certainly heard of the US state by the same name. I'm aware of the country now, obviously, and even learned where it was on a map, because I hadn't heard of it before then. My point being that based on my own personal experience, there can be some legitimate concern that not everyone who reads this may necessarily know immediately that the Georgia being referred to is a country, and not the state.
Although I'd still agree that talking down to your audience as if they may not already know this is probably bad form, because really, it's something that anyone can look up.
