Tigerhawk highlights this AP report that describes how Iran is getting spare parts for its F-14s. He writes:

So we shut down our Tomcat program and shipped all the spare parts to the office in the Pentagon charged with squeezing every penny out of surplus stuff, whereupon we auctioned them off to front companies which resold the stuff to, er, Iran. As if there were any other buyer for surplus F-14 parts.

Probably too late now, but the parts should have been sabotaged before resale. Or maybe they were. Be nice if the Iranians thought that.
