There's no way around that, bta. So, in the Iranian view, the threats that Netanyahu has made are at least equivalent to their own threat, imho.
Seeing as how the Iranians have very little way to back up their threats, I see them more in the realm of rhetoric - ugly and unacceptable rhetoric, but words, as compared to actual nukes possessed by the Israelis.
Here's some other relevant facts:
The Myth of the Iranian Nuclear Threat
The Israeli Defense Forces Chief of Staff, Daniel Halutz, has categorically denied that Iran represents an immediate nuclear threat to Israel, let along the United States. According to Haaretz (12/14/05), Halutz stated that it would take Iran time to be able to produce a nuclear bomb which he estimated might happen between 2008 and 2015.
Israel's Labor Party officials do not believe that Iran represents an immediate nuclear threat and that the Sharon government and the Likud war propaganda is an electoral ploy. According to Haaretz, "Labor Party officialsaccused Prime Minister Ariel Sharon, Defense Minister Shaul Mofaz and other defense officials of using the Iran issue in their election campaigns in an effort to divert public debate from social issues".
In a message directed at the Israeli Right but equally applicable to AIPAC and the Presidents of the Major Jewish Organizations in the US, Labor member of the Knesset, Benjamin Ben-Eliezer rejected electoral warmongering: "I hope the upcoming elections won't motivate the prime minister and defense minister to stray from government policy and place Israel on the frontlines of confrontation with Iran. The nuclear issue is an international issue and there is no reason for Israel to play a major role in it" (Haaretz, December 14, 2005).
Israeli intelligence has determined that Iran has neither the enriched uranium nor the capability to produce an atomic weapon now or in the immediate future, in contrast to the hysterical claims publicized by the US pro-Israel lobbies. Mohammed El Baradei, head of the United Nations International Atomic Energy Agency (IAEA), which has inspected Iran for several years, has pointed out that the IAEA has found no proof that Iran is trying to construct nuclear weapons. He criticized Israeli and US war plans indirectly by warning that a "military solution would be completely un-productive".
More recently, Iran, in a clear move to clarify the issue of the future use of enriched uranium, "opened the door for US help in building a nuclear power plant". Iranian Foreign Ministry spokesman, Hamid Reza Asefi, stated "America can take part in the international bidding for the construction of Iran's nuclear power plant if they observe the basic standards and quality" (USA Today, Dec. 11, 2005).

The article goes on to say that in a move to clarify it's intent, Iran offered to allow the US to help in building a nuclear power plant.
