The study by the Carnegie Endowment for International Peace said that U.S. nuclear weapons spending — excluding classified programs — makes up 10 percent of the total defense budget, consumes 67 percent of the Department of Energy’s budget, and exceeds the total amount spent on international diplomacy and foreign aid, which is $39.5 billion. It also exceeds spending on technology, general science and space, which is $27.4 billion.
“Nuclear weapons pose the most serious threat to human life,” Cherie Eichholz, executive director of Washington PSR, wrote in an e-mail. “The numbers are highly disturbing, as is the fact that less than 10 percent of the $52 billion went toward slowing the proliferation of nuclear weapons and technology.”
