The push by the Trump administration to persuade Tehran to give up its nuclear program came after the U.S. and other world powers in 2015 reached a long-term, comprehensive nuclear agreement that limited Tehran’s enrichment of uranium in exchange for the lifting of economic sanctions.

President Donald Trump rejected a plan presented by Israel to the U.S. to kill Iran’s Supreme Leader Ayatollah Ali Khamenei, according to a U.S. official familiar with the matter. The Israelis informed the Trump administration in recent days that they had developed a credible plan to kill Khamenei.
