To the imported British media personality I saw on television last night:

It's pronounced America, not Americer. At least do us the decency of learning to speak your language properly before emigrating to our TV sets. If my Argentinian ex-boyfriend can pronounce it correctly despite speaking SIX other languages fluently (and as far as I can tell that's several THOUSAND other words he knows to get confused with), then I'm certain it won't be much of a challenge for you in your native tongue.

Seriously. Eliza Doolittle could do it; you can too.
