Sure, hahaha, look at the stupid Americans being stupid!
So, let's turn this around. European friends, would you be able to correctly label all the 52 US states on a blank map of the US? I know for certain that I would not. Heck, I'm not sure I would be able to fill in the map of Europe correctly. I'm not sure I would know which Balkan state is which. Which one is Romania, which one is Hungary? I don't think I could point them out reliably. And yet I do not consider myself stupid (and, I hope, neither do others).
Let's go a bit further afield. Could you correctly label African nations? Countries in Asia? Point out Kyrgyzstan on a blank world map? (Though I'm reasonably sure that nwhyte and blacksearoamer could pull that last one off.)
Let's not kid ourselves. It's good to be aware of what happens in other countries. Not being able to point them out precisely on a map does not automatically mean you're stupid or dis-interested.
