There has been so much discussion of what the Senate is cutting from the House version of the economic stimulus plan that it is easy to overlook the fact that the Senate version also adds new expenditures. Joe Cirincione, president of the Ploughshares Fund, calls attention to one such add: $1 billion “for weapons activities” at the laboratories and factories run by the National Nuclear Security Administration (NNSA). Created in 2000, the NNSA, a semi-autonomous agency within the Department of Energy, is responsible for overseeing the nation’s nuclear weapons complex. Since its inception, it has been plagued by controversies regarding inefficiency and lax security. The NNSA already has an annual budget of $9.1 billion, two thirds of which goes to “weapons activities.”
