http://www.dni.gov/press_releases/20071203_release.pdfA. We judge with high confidence that in fall 2003, Tehran halted its nuclear weapons
program1; we also assess with moderate-to-high confidence that Tehran at a minimum is
keeping open the option to develop nuclear weapons. We judge with high confidence
that the halt, and Tehran’s announcement of its decision to suspend its declared uranium
enrichment program and sign an Additional Protocol to its Nuclear Non-Proliferation
Treaty Safeguards Agreement, was directed primarily in response to increasing
international scrutiny and pressure resulting from exposure of Iran’s previously
undeclared nuclear work.
• We assess with high confidence that until fall 2003, Iranian military entities were
working under government direction to develop nuclear weapons.
• We judge with high confidence that the halt lasted at least several years. (Because of
intelligence gaps discussed elsewhere in this Estimate, however, DOE and the NIC
assess with only moderate confidence that the halt to those activities represents a halt
to Iran's entire nuclear weapons program.)
• We assess with moderate confidence Tehran had not restarted its nuclear weapons
program as of mid-2007, but we do not know whether it currently intends to develop
nuclear weapons.
• We continue to assess with moderate-to-high confidence that Iran does not currently
have a nuclear weapon.
• Tehran’s decision to halt its nuclear weapons program suggests it is less determined
to develop nuclear weapons than we have been judging since 2005. Our assessment
that the program probably was halted primarily in response to international pressure
suggests Iran may be more vulnerable to influence on the issue than we judged
previously.
