it was Robert Gates - (I was there) and it was only about US attitude to RAAF getting F-22 if they asked for it. RAAF made it clear that they didn't need and/or want F-22not entirely sure on this but I'm trying to find it, I remember some high ranking official was agreeable to Australia getting nuclear powered submarines it was around the same time that they would have no problems with RAAF having F22 Raptor, cant remember who it was and position.
The nuke sub discussions that came up in 2007 were only enthusiastically supported by US industry and were rapidly dismissed as a non starter due to SecDef/SecNav/State issues
