I would think (hope) that Americans would be able to locate major countries around the perimeter of Europe. It certainly shouldn't be an issue locating Great Britain (which is physically a bit more identifiable than the UK), France, Portugal, Spain, Italy, Greece, Turkey (which is mostly in Asia), and Russia. Norway, Sweden, and Finland should be pretty easy. Estonia, Latvia, and Lithuania should be locatable, although I can see people easily mixing them up. And Denmark sticks out like a sore thumb. Central and eastern Europe would be tougher, in part because the borders have changed so much over the years. Ukraine stands out because it's so big, though. In Asia, I'd hope that people could locate Russia, Japan, China, India, Saudi Arabia, and Turkey. In Africa, I would think that people could spot Egypt and Morocco. And in South America, I'd think that Brazil, Argentina, and Chile would stand out.
