if it results in a return to the moon, then I suppose it will be worth it ..

one point though -

The latest version of the RFP for the CEV program no longer includes the Cargo Delivery Vehicle. This was a version of the Block 1 CEV which was designed to deliver large indivisible modules of unpressurized cargo to the International Space Station. This would include such vital components as the Control Moment Gyros which are essential to maintaining the station's attitude.

Without the CDV, there is no way to deliver new CMGs after the Shuttle retires in 2010. Clearly, it is not expected that the ISS will still need them in the 2010-2016 period. This implies that the ISS won't be there at that time - or at least that NASA will not be supporting it..

If there are no CDVs how would they expect to establish even a semi-permanent lunar station? Wouldn't lunar CDVs be a type of upgrading of these ones, now cancelled? Without those all we would be left with are slightly bigger and longer expeditions than Apollo. If we have to sacrifice Mars and the ISS then at least we should get a properly equipped outpost, hopefully in Tycho for instance.
