March 21, 2013 - Khamenei, in a televised speech, threatens Tel Aviv and Haifa by stating "at times the officials of the Zionist regime (Israel) threaten to launch a military invasion but they themselves know that if they make the slightest mistake the Islamic Republic will raze Tel Aviv and Haifa to the ground."

October 21, 2015 - Khamenei conditionally approves the nuclear deal signed between his country and six world powers in July.
February 7, 2017 - According to his website, Khamenei tells a gathering of Iran's air force commanders in Tehran, "We however thank this new guy in the White House, since he largely did the job we had been trying to do in the past decades: to divulge the true face of the US. We had been working to show the world the depth of corruption in US government and ranks and files of the ruling elite; [US President Donald] Trump did it in few days after coming to the White House."
