Iran and Israel both sceptical over US deal If we see errors being made by officials, the revolutionary forces will issue the necessary warnings,' he added, calling for the US to lift crippling economic sanctions and accept the country's right to a nuclear programme. In a sign of his determination to press ahead, Mr Rouhani has asked aviation authorities to study the possibility of resuming direct flights between Iran and the US, which have been suspended for more than 30 years. In Washington, meanwhile, Mr Netanyahu used an Oval Office meeting with Mr Obama to demand that the US remain "clear-eyed" about the sudden softening in Tehran which he said remained committed to the destruction of Israel. "We say in Hebrew that the bottom line is important - and that is that Iran does not get nuclear weapons," Mr Netanyahu said, urging that sanctions against Iran should be tightened if they continued to enrich uranium when planned negotiations in Geneva on October 15 and 16 got under way. Mr Obama said the US shared Israel's determination that Iran should not develop nuclear weapons and that military options remained "on the table" when it came to Iran, while avoiding the contentious issue of Iran's enrichment. "It is absolutely clear that words are not sufficient," Mr Obama said, promising actions that would give the international community confidence that in fact Iran was meeting their international obligations fully and "are not in a position to have a nuclear weapon." Mr Netanyahu replied: "Iran's conciliatory words have to be matched by real actions - transparent, verifiable, meaningful actions. Iran is committed to Israel's destruction. Israel has support among hawks in Washington who are sceptical that after a decade of obfuscation over its nuclear programme, Iran's assurances can suddenly be taken at face value. In a bid to demonstrate the threat still posed by Iran, Shin Bet, the Israeli domestic intelligence agency paraded an Iranian spy who was arrested on September 11 on suspicion of spying for the Revolutionary Guards after taking pictures of the US embassy in Tel Aviv. "Netanyahu's nightmare is an Obama administration that, in its eagerness for a historical deal with Iran, trades away short term sanctions relief for Iranian nuclear concessions that become increasingly less enforceable and verifiable over time," said Mark Dubowitz of the Foundation for Defence of Democracies, a think tank that has argued for a tough line against Tehran. Analysts said that the prospects of a deal between the US and Iran depended on both sides being able to claim victory - Tehran in the lifting sanctions and recognition of its right to enrich uranium, and Washington in heading off Iran's dash to build a bomb. Less clear, however, is how such an outcome could be construed as a victory for Mr Netanyahu who has demanded that Iran not be allowed to enrich its own uranium, but should instead receive controlled amounts of reactor-grade fuel from abroad. "There's a victory speech on both the American and the Iranian sides, but the question whether there is a victory speech that the third - Israeli - leg of this negotiation is willing to make?" said Daniel Levy, Middle East director at the European Council on Foreign Relations.
