Karim Sadjadpour, an Iranian specialist at the Carnegie Endowment for International Peace, notes that Iranian government entities began to erect billboards and signs with the “wipe off” phrase in English.

The fact that this lie is repeated over and over shows you how thoroughly Zionist propaganda has propagated through the US media.
