Is Steven Chu’s emphasis on the “Energy” in “Department of Energy” responsible for the nuclear weapons management mess?

Energy Secretary Steven Chu

Coral Davenport has an excellent piece at the National Journal this morning looking at Steven Chu’s tenure at the Department of Energy. Chu came as a distinctly non-politician cabinet member to an agency the primary job of which was really nuclear weapons in an administration that wanted to actual act on the “Energy” in the agency’s name:

At the time Chu took the helm at the Energy Department, it actually played very little role in shaping energy policy. Its chief purview was to oversee the nation’s nuclear weapons arsenal. Obama’s plan was to push a comprehensive energy and climate change bill through Congress, raising $150 billion for clean energy research over a decade. Chu was to oversee a transformation of the department into an international driver of clean energy development.

My question is whether problems in management of the nuclear weapons program, frequently documented here, are in any way a result of the shift in senior agency management attention away from the nuclear weapons mission? (The back story here is that Chu is widely reported to be leaving the department.)
