Well, NORMALLY American English has bastardized the pronunciation of words from their original British English form, but that's actually not the case here. The original British English pronunciation is the one that rhymes with 'race.' This is evident in the many rhymes by British poets using the word from hundreds of years ago, like your friend and mine, Lord Byron.

I don't understand how or why modern British English speakers say it differently than older British English speakers clearly did. They're forced, however, to concede that either a) all other American English language changes are valid and correct, or b) the way they say "vase" is wrong.

So, Euros, which is it?
