William Tobey, Senior Fellow at the Belfer Center for Science and International Affairs, writes in the Wall Street Journal that the nuclear agreement with Iran does not provide stringent enough verification measures to ensure that Iran is abiding by the agreement. Specifically, he notes that in some cases, as many as twenty four days may elapse before inspectors arrive at a site to investigate, which will give Iran time to hide evidence of wrongdoing. He also argues that the deal fails by not requiring Iran to submit a full declaration of the past military dimensions of the program, meaning any actions that could have been carried out in the explicit pursuit of a nuclear weapon. Without this declaration, he argues, the agreement does not set a baseline for inspections, making it much harder for the deal to be enforced.
