A high-level overview of Barack Obama's 2010 budget, released today, leaves more questions than answers about funding for the U.S. nuclear weapons program:

Development work on the reliable replacement Warhead will cease, while continued work to improve the nuclear stockpile’s safety, security, and reliability is enhanced with more expansive life extension programs.
