I took the road less traveled by (Part 1912)....

 MAPS!

Today's map show all the nations that do NOT have an A in their names. 

Not sure if I can name them all: Mexico, Belize, Peru, Chile, Morocco, Benin, Cote d'Ivoire, Lesotho, United Kingdom, Belgium, Finland, Luxenbourg, Greece, Turkey, Egypt, Yemen, Philippines.  There probably are other small nations that don't show up on the map here well that don't have A's either, but I don't see them, nor can I think of them.
