I was able to read it using a special Firefox extention that does magic things to non-live links.

That article is being very dishonest. For one thing, they even admit that Ahmadinejad said, "this Jerusalem occupying regime", but they decide that Jerusalem occupying regime means the state of Israel itself and all of its people rather than its actual meaning, which is the regime in Israel (the government). They also allude to the existence of missiles with the saying wipe Israel off the map, but they offer no evidence of it nor the actual words in Iranian pre-translation (assuming such things exist, which we so far have no evidence of). I am inclined to view this particular source as a propaganda source.
