> Odd that this statement does not get equal treatment in the media?

Not that odd, because of its inconsistency with more frequent, more bellicose statements against Israel, combined with the nuclear program and disregard of the UN. Which would it be more prudent to believe?

Talk in international relations is cheap.

There is no reason other than fear for its own existence for Israel to attack Iran, which is many times its size. Iran can protect itself and the entire region by cooperating with the UN, laying off the hostile rhetoric, and ending the enrichment of uranium beyond internationally recognized peaceful requirements. The cost to Iran? Virtually nothing.
