* Israel avoided NPT review conferences since 1995
* Now sees common cause with Arabs alarmed by Iran (Adds diplomats on expectations about NPT review conference)
By Dan Williams
JERUSALEM, April 26 (Reuters) - Israel will take part as an observer in a major nuclear non-proliferation conference that opens at the United Nations on Monday, ending a 20-year absence in hope of fostering dialogue with Arab states, a senior Israeli official said.
Assumed to have the Middle East’s sole nuclear arsenal, and having never joined the nuclear Non-Proliferation Treaty, Israel has stayed away from gatherings of NPT signatories since 1995 in protest at resolutions it regarded as biased against it.
In a position laid out by then Foreign Minister Shimon Peres in 1995, Israel has said it would consider submitting to international nuclear inspections and controls under the NPT only once at peace with the Arabs and Iran. Those countries want Israel curbed first.
With Middle East upheaval and the disputed Iranian nuclear programme often pitting Tehran-aligned Shi‘ite Muslims against Sunni Arabs, a senior Israeli official saw in the April 27-May 22 NPT review conference a chance to stake out common causes.
Israel deems Iran its top threat. The Islamic Republic has said it seeks only nuclear energy, not bombs, from uranium enrichment. Six global powers are negotiating a comprehensive nuclear deal with Iran - a process Israel has denounced, fearing it will not restrain Tehran’s atomic activities sufficiently.
“We think that this is the time for all moderate countries to sit and discuss the problems that everyone is facing in the region,” the Israeli official, who requested anonymity given the sensitivity of the subject, told Reuters on Sunday.
“I see this, coming as an observer to the conference now, as trying to demonstrate our good faith in terms of having such a conversation. We need direct negotiations between the regional parties, a regional security conversation, a conversation based on consensus. This (attendance at the NPT conference) is meant not to change our policy. It’s meant to emphasise our policy.”
The question of sequencing - if peace should precede disarmament - has helped mire negotiations on the creation of a Middle East free of weapons of mass destruction. An Egyptian plan for an international meeting laying the groundwork for such a deal was agreed at the last NPT review conference, in 2010.
Western diplomats at the U.N. say that Egypt is unlikely to take as aggressive a stance against Israel now as it has at past NPT meetings, and that Israel and Arab nations worried about the Iran nuclear deal are united for the time being by a common fear that the United States might concede too much to Tehran in the talks.
The Israeli official doubted the deadlock would be resolved at the pending NPT conference - anticipating, instead, an “Arab proposal that would not adopt the position of direct engagement” with Israel.
Still, the official described the NPT conference as a chance to build on opposition Israel shared with some Arab countries to the April 2 outline nuclear deal between world powers and Iran.
The conference “doesn’t contradict a broader possible outreach,” the official said. Without naming specific countries, the official said some Arabs appeared less attentive to Israel’s non-NPT status as they were “too busy with bigger problems”.
Among these might be Egypt, which had long been vocally opposed to Israel’s nuclear opacity but has recently closed ranks with its neighbour against common Islamist adversaries.
“Our initiative for a Middle East free of non-conventional weapons is a principle. It will not change. But nothing is against Israel itself. It’s for everyone - Iran, Israel, everyone,” an Egyptian official said on condition on anonymity.
“Will we go and pressure Israel (at the conference)? I don’t think so. I don’t think the pressure will be intolerable.” (Additional reporting by Louis Charbonneau in New York; Editing by Jeffrey Heller, Mark Heinrich and Frances Kerry)
