The Greek Air Force (no jokes please) is now on strike.
A former (Spanish) colleague of mine at Moody's used to divide countries into two categories: serious and unserious. When someone wanted to upgrade an Argentina, he would say "They are not a serious country."
Well, I don't think that there is any military in the world that has ever gone on strike (although it is true that certain unserious European militaries are unionized, but "peace is their profession").
So Greece now suggests that there should be three country categories instead of two: serious, unserious, and Hellenic.
