Did Iran and the U.S. both consider the Taleban to be an enemy after the 9/11 attacks?

True-true. according to ali m. ansari, professor of iranian history at the university of st. andrews, [k]hatami, moved quickly to offer his condolences to the us president [after the 9/11 attacks]. [t]he iranians soon recognized the opportunity that now confronted them. the united states was determined to dismantle al qaeda, and in the face of taleban obstinacy decided on the removal of the taleban. nothing could be more amenable to the iranians, who had been waging a proxy war against the taleban for the better part of five years. the collaboration which took place both during and after the war against the taleban seemed to inaugurate a period of détente between iran and the united states it came as something of a shock therefore to discover that president bush had decided to label iran part of the axis of evil now it appeared that the [iranian] hardliners within the regime had been correct after all; the united states could not be trusted ( ali m. ansari; modern iran: the pahlavis and after second edition; pearson education; great britain: 2007; pp. 331-332.)
