After almost thirty years, the US is suddenly contemplating a return to nuclear testing. The Senate Armed Services Committee version of the FY21 National Defense Authorization Act provides “no less than $10 million” to “carry out projects related to reducing the time required to execute a nuclear test if necessary.” This follows reports in May that senior Trump administration officials were considering conducting a test as a way to pressure Russia and China to engage in nuclear arms control negotiations. On June 24, the administration’s envoy for arms control told reporters that he was “unaware of any particular reason to test at this stage,” but also refused to rule out the possibility, asking “why would we?”
