A key additional point to add here is that the House and Senate Energy and Water Committees have adopted the $624 million increase for NNSA in FY2011.  This is significant for three reasons.

First, the House Energy and Water Subcommittee has traditionally not been kind to NNSA's budget requests.  The fact that they've bought into it this year is an important step.  Second, the adoption of the increases by the the subcommittees was due in no small part to administration's dedication to pushing for its budget with Congress.  Third, a big reason the House adopted the requested increase is that this administration has actually put forth a credible plan to maintain, refurbish, and modernize the stockpile, something that certainly couldn't be said of the Bush administration's wild goose chases for things like RNEP, low-yield weapons, and the RRW.  

Finally, I don't want to hear that the House appropriators cut $19 million from that request.  The Senate Energy and Water Committee actually added $10 million.  If you split the difference (which is premature at this point because there might not be a decrease at all when it's all said and done) that's a decrease of only $4.5 million out of a budget of $7 billion.
