Belgium??? I checked the California State World History Standards (
http://www.cde.ca.gov/be/st/ss/hstgrade10.asp) for high school and I don't think there is anything specifically about Belgium, except where it has to do with larger bits of European history. Since California was once a part of Mexico and since we share a border, Mexico comes up a bit more frequently- from pre-Columbian empires to the Revolution during the last century.
I guess the positive thing about that is that we don't really have a set of prejudices and stereotypes about Belgians...
An old friend of my sister, Susana Guzman is an opera singer. In those Mexico Tourism commercials, she can be heard whispering "Mexico" in hushed sexy tones.
Mexico is where the current VW Beetle comes from, at least here in the US... Mexico also produces some cell phones, computers, components and iPods.
Bimbo/Gamesa cookies, Jamaica, Horchata, Bitter Chocolate, Telenovelas, Silver from Taxco, BIG belt buckles, and old American pick up trucks...
