I bet half the nation pronounces it that way. I do if I am not thinking about it. Guaran-damn-tee I got more brain power than you, dummie. ... 
This complaint is pretty rich, coming from a dude(tte) who consistently mispronounces and misspells aluminium - just ask any EuroLand about that!
For my part, as long as he does his part of the job of keeping nukes from exploding in this country, he could pronounce it "mashed potatoes" for all I care!
Chew on this, DU folk that chance to see this post:
* Neville Chamberlain placated Hitler and got WW2;
* Bill Clinton placated and brought off Kim Jong Il, and NoKo developed nukes despite "promising" not to;
* Barack Obama tried to placate and buy off Iran, and Iran is going full steam ahead with its nuclear program.
Chamberlain left Churchill and the world a mess.
Bill Clinton created the mess Trump is trying to deal with.
What R is going to have to deal with Obama's mess?!
