In a speech to the
"I wish I could believe Rouhani, but I don't, because facts are stubborn things," Netanyahu said.

The pressure on Iran must continue, Netanyahu said, especially sanctions against the country, until Iran fully dismantles its nuclear program.

"This is his nature, to lie …," Zarif said. "Over the past 22 years, the regime, Israel, has been saying Iran will have nuclear arms in six months. The continuation of this game, in fact, is based on lying, deception, incitement and harassment."
He also called Netanyahu the "most isolated individual" at the UN.
