U.S. buying time to strengthen the military option

"The intrusive inspections of the nuclear deal will also strengthen the military option by allowing the United States and its allies to better map out Iran’s nuclear program. Although the broad contours of Iran’s nuclear facilities are well known, their exact dimensions, as well as the entire supply chain, almost certainly eludes the United States and its allies." "Most importantly, the new nuclear deal will give the United States and Israel time to develop the capabilities they need to carry out a military strike." "Moreover, while Iran’s nuclear program will be frozen in place for over a decade, the United States and Israel will be free to strengthen their military capabilities." (thanks Amir)
