Netanyahu has long accused Iran of developing a nuclear weapon and went on a global campaign against the Obama deal. He painted the nuclear program as an existential threat to Israel and the world, and said the agreement was too weak to contain it. Israel remains the Mideast’s only nuclear-armed state, an advantage it would like to keep.

Iran will hold talks in Rome on Friday with European parties to their now moribund 2015 nuclear deal, its foreign minister said on Wednesday, as both sides seek to position themselves ahead of a new round of U.

The announcement of the delay in talks came as news broke that President Trump is ousting his national security adviser, Michael Waltz, according to people familiar with the situation. Mr. Waltz, a well-known hawk on Iran policy, had demanded that Iran dismantle its entire nuclear program.
