Israeli officials told Channel 10 on Friday that they are convinced the Obama administration has already agreed to most of Iran’s demands in the P5+1 negotiations over the Islamic Republic’s nuclear program.According to unnamed officials, Washington “has given the Iranians 80 percent of what they want” out of the negotiations, Channel 10 is reporting.Jerusalem officials appear alarmed at the prospect that the United States will soon strike a deal with the Iranian regime that will leave it with a “breakout capacity” of months during which it can gallop toward a nuclear bomb.The practical significance of the American compromises in the talks is that Iran will be permitted to keep over 7,000 centrifuges, enough for the Iranians to produce enough enriched material to sprint toward the bomb within a matter of months.These developments have apparently fueled Prime Minister Benjamin Netanyahu’s sense of urgency in traveling to Washington and addressing Congress in hopes of lobbying American lawmakers to pass tougher sanctions against the Islamic Republic.Channel 10 reported that Netanyahu spoke to a number of Democratic lawmakers in Congress. The premier sought to assuage their concerns that the Israeli leader was using his speech before a joint session of the house in order to undermine Obama’s foreign policy.Netanyahu’s scheduled speech sparked an uproar in Washington, with Democrats accusing House speaker John Boehner of inviting the premier to speak before Congress as a means of whipping up opposition to the Obama administration’s talks with Iran.Sources in Jerusalem told Channel 10 that the prime minister views the Iranian nuclear issue as one of paramount importance for Israel’s security. The urgency of the matter – and not partisan politics - is what motivated Netanyahu to violate diplomatic protocol and accept the Republican leadership’s invitation to address the Congress on the need for more sanctions against Iran, Channel 10 quotes officials as saying.Netanyahu reiterated Friday during a visit to soldiers wounded in Wednesday’s attack near the Lebanon border that Israel is adamantly opposed to the agreement the world powers are negotiating with Iran.“It is possible to solve procedural problems related to my appearance in the United States,” he said, “but if Iran obtains nuclear arms that is something that will be a lot more difficult to solve, and that is what we are opposed to and are focusing on.”“We are in a continuous struggle with Iran which is opening new fronts against us, which is engaged in terrorism in the Middle East and throughout the world,” Netanyahu said. “This is the same Iran that the world powers are now working toward an agreement that would leave in its hands the ability to develop a nuclear bomb. That is an agreement we are opposed to.”Netanyahu said Israel is continuously coming under attacks organized by Iran. “Iran is trying to uproot us from here, but they will not succeed,” he said. “We put down roots here , and will continue to do so, and will continue to make the country flower and create new life.”Herb Keinon contributed to this report.
