Israel is planning to bomb the nuke facilities.
More specifically Israeli military sources reveal that Israel's current and probably next Prime Minister Ariel Sharon ordered Israel's armed forces to prepare for air strikes on uranium enrichment sites in Iran According to the London Times the order to prepare for attack went through the Israeli defense ministry to the Chief of Staff. During the first week in December, "sources inside the special forces command confirmed that 'G' readiness the highest state for an operation was announced" (Times, December 11, 2005).
On December 9, Israeli Minister of Defense, Shaul Mofaz, affirmed that in view of Teheran's nuclear plans, Tel Aviv should "not count on diplomatic negotiations but prepare other solutions". In early December, Ahron Zoevi Farkash, the Israeli military intelligence chief told the Israeli parliament (Knesset) that "if by the end of March, the international community is unable to refer the Iranian issue to the United Nations Security Council, then we can say that the international effort has run its course".
In other words, if international diplomatic negotiations fail to comply with Israel's timetable, Israel will unilaterally, militarily attack Iran. Benjamin Netanyahu, leader of the Likud Party and candidate for Prime Minister, stated that if Sharon did not act against Iran, "then when I form the new Israeli government (after the March 2006 elections) we'll do what we did in the past against Saddam's reactor." In June 1981 Israel bombed the Osirak nuclear reactor in Iraq.
Even the pro-Labor newspaper, Haaretz, while disagreeing with the time and place of Netanyahu's pronouncements, agreed with its substance. Haaretz criticized "(those who) publicly recommend an Israeli military option" because it "presents Israel as pushing (via powerful pro-Israel organizations in the US) the United States into a major war." However, Haaretz adds "Israel must go about making its preparations quietly and securely not at election rallies." (Haaretz, December 6, 2005). Haaretz's position, like that of the Labor Party, is that Israel not advocate war against Iran before multi-lateral negotiations are over and the International Atomic Energy Agency makes a decision.
