Israeli Prime Minister Benjamin Netanyahu addresses a joint session of the US Congress

Israeli prime minister Benjamin Netanyahu has told the US Congress that negotiations under way between Iran and the United States would “all but guarantee” that Tehran will get nuclear weapons, a step that the world must avoid at all costs.

“Iran has proven time and again that it cannot be trusted,” no matter what it says about permitting verification of the terms of any accord designed to prevent it from getting such weapons, he said.

“The greatest danger facing our world is the marriage of militant Islam with nuclear weapons,” he said in remarks before a packed House chamber.

Mr Netanyahu spoke shortly after US secretary of state John Kerry met for more than two hours in Switzerland with Iranian foreign minister Mohammad Javad Zarif in the hope of completing an international framework agreement later this month to curb Tehran’s nuclear ambitions.

The Israeli leader’s appeal also came two weeks before elections in which he is seeking a new term – and after the invitation to address Congress extended by House Speaker John Boehner, a Republican, triggered a political furore in the United States. More than four dozen House and Senate Democrats said in advance they would not attend the event, a highly unusual move given historically close ties between the two allies.

The White House expressed its displeasure with the appearance by word and deed, dispatching vice president Joe Biden on an overseas trip that meant he did not fill his customary seat behind the House rostrum during the speech. Nor did Mr Netanyahu meet at the White House with Mr Obama on his trip to the United States.

The prime minister was greeted with a roaring welcome as he walked down the same centre aisle of the House chamber that presidents tread before their annual State of the Union speeches.

He also sought to smooth over any political unpleasantness, thanking Mr Obama lavishly for the help he has given Israel since he became president. In a grace note, he took a moment to mention Senate Democratic Leader Harry Reid, who is back at work after suffering an eye injury in an accident at home.

At the same time, Mr Netanyahu was unrelenting in his condemnation of the negotiations the administration is conducting with Tehran.

He said that with the concessions the United States was prepared to make Iran would not only gain nuclear weapons, but would also eventually become free of international economic sanctions. As a result, he said, it would be emboldened to finance even more terrorism around the Middle East and the world.

The result for Iran, he said, would be “aggression abroad and prosperity at home”.

Instead, he said that if Iran wants to be “treated like a normal country, it ought to behave like a normal country”.
