In an address, the Israeli prime minister said Iran had taken steps to weaponize enriched uranium and was on the cusp of developing a nuclear weapon.

Netanyahu strongly opposed the Joint Comprehensive Plan of Action (JCPOA), the nuclear deal made with Iran and world powers in 2015. He believed it would only delay Iran’s nuclear goals while freeing up funds that could be used for military activities and support for its allies.

With Donald Trump mulling whether to send in American bunker-busting bombs to deal a crushing blow to Iran’s nuclear facilities, doubts remain about just how close Iran is to creating a nuclear bomb.
