Somehow it is annoying for a lot people when appreviations are used and people expect to know the context.
Would you know the Context when I talk about FJS buying tanks that not even the manufacturer liked, or the planes that became known as "the widow maker"
No, because we're used to get full names... I didn't even know Hillary Clinton has a middle name. In german media she's always just Hillary Clinton.
And I think this is some US defaultism the world shakes it's head over.
