Veteran Iran watchers in the United States were quoted by public broadcaster NPR as saying that while the US attacks could have delayed Iran's nuclear program, bombing can achieve only so much.
"The program has been seriously set back, but there's a lot of odds and ends," David Albright, the president of the Institute for Science and International Security, told NPR.
Professor Jeffrey Lewis at the Middlebury Institute of International Studies said air attacks were not a cure-all.
"Even the most brilliant bombing campaign, probably is not going to get us where we want to be," Lewis said.
