Even the NY Times reports that there is reason for concern:
"The International Atomic Energy Agency, in an unusually blunt and detailed report, said Monday that Iran’s suspected research into the development of nuclear weapons remains “a matter of serious concern” and continues to need “substantial explanations.” The nine-page report accused the Iranians of a willful lack of cooperation, particularly in answering allegations that its nuclear program may be pointed less at energy generation than at military use."
Many of my acquaintances who fall on the left side of the political aisle seem to suggest that Iran presents no serious reason for concern. Conservatives ought to demand that they explain themselves, especially given information like the above.
