Not according to the Arms Control Association:
The broad outline in the IAEA’s latest report on the military dimensions of Iran’s program is not new, but rather, provides greater detail regarding weapons-related activities outlined in previous public reports.
The IAEA report and annex reinforce what the nonproliferation community has recognized for some time: that Iran engaged in various nuclear weapons development activities until 2003, then stopped many of them, but continued others.
The activities documented in the IAEA report, including research related to nuclear warheads, underscore that Tehran’s claims that it is only seeking the peaceful use of nuclear energy are false.
Iran’s warhead work also contradicts its obligation not to pursue nuclear weapons under the nuclear Nonproliferation Treaty (NPT), under which states parties commit “not to seek or receive any assistance in the manufacture of nuclear weapons or other nuclear explosive devices.”
The report suggests that Iran is working to shorten the timeframe to building the bomb once and if it makes that decision. But it remains apparent that a nuclear-armed Iran is still not imminent nor is it inevitable.
The report should prompt greater international pressure on Tehran to respond more fully to the IAEA’s questions, allow for more extensive inspections of its nuclear facilities, engage more seriously in talks on its nuclear program, and to agree to confidence building steps to help resolve the crisis.
In other words, Tehran is moving towards being capable of building a nuclear bomb and war-head delivery system, does not have one now nor is the IAEA is reporting an imminent threat.
The ambiguity in Iran’s intentions, not to mention those of Israel and the US, also shows no sign of lifting anytime soon.
