Yes, his best aircraft, which are useless when put up against F-16's, F-14's, or F-18's. By modern standards obsolete.
Even still, it is a false analogy. Saddam sent them to Iran because he knew that the US airforce would utterly destroy them. If Iran had them, at least there was a chance that he might get them back later. Plus they did not strengthen Iran by all that much. Iran already had a better airforce, equipped with US planes purchased during the time of the Shah. Finally, Iran knows Iraq has WMD, so an attack from Iran is unlikely in any event. Giving weapons to Al Qaeda is in no way comparable.
