The Israeli prime minister made it clear that Israel was prepared to face Iran alone if necessary.
He said: “I want there to be no confusion on this point. Israel will not allow Iran to get nuclear weapons. If Israel is forced to stand alone, Israel will stand alone. Yet in standing alone, Israel will know that we will be defending many, many others.”
His UN speech followed meetings with President Barack Obama and Secretary of State John Kerry in Washington on Monday, where he stressed the need to maintain strong economic sanctions against Iran.
Following their meeting, Mr Obama assured Mr Netanyahu that Iran’s conciliatory words to the US would not be enough for the sanctions to be lifted.
He said: “We have to see if in fact they are serious about their willingness to abide by international norms and international law and international requirements and resolutions.”
