Right now, there is a great deal of fuss over the comments by the president of Iran, who wants Israel to be "wiped off the map".
It seems to me that it was well-known for a while that Iran had this goal; the only new elements are that it is the active president who does the comments, and that he does so quite openly.
I understand that Iran also has some other objectives, such as eliminating the United States, and eliminating the Bahá'í Faith both within and outside Iran.
Difference in opinions hath cost many millions of lives: for instance, whether flesh be bread, or bread be flesh; whether whistling be a vice or a virtue; whether it be better to kiss a post, or throw it into the fire... (from Gulliver's Travels)
