Pronouncing Iraq

[sagehen]

Are the various pronunciations of "Iraq" -- EYE rack, EAR rack, EE rack --
linked to dialects, to professional domains, e.g., military, academic,
diplomatic, &c., to class/register  or NOTA?

Is the romanized spelling of Arabic that omits U after Q meant to convey a
particular sound distinct from K, or did it become conventionalized  for
some other reason?

Just ruminating....
