A valuable and interesting op-ed from Henry Kissinger. The following passage deserves mention and further commentary in response to the questions that it raises:
The "Key Judgments" released by the intelligence community last week begin with a dramatic assertion: "We judge with high confidence that in fall 2003, Tehran halted its nuclear weapons program." This sentence was widely interpreted as a challenge to the Bush administration policy of mobilizing international pressure against alleged Iranian nuclear programs. It was, in fact, qualified by a footnote whose complex phraseology obfuscated that the suspension really applied to only one aspect of the Iranian nuclear weapons program (and not even the most significant one): the construction of warheads. That qualification was not restated in the rest of the document, which continued to refer to the "halt of the weapons program" repeatedly and without qualification.
The reality is that the concern about Iranian nuclear weapons has had three components: the production of fissile material, the development of missiles and the building of warheads. Heretofore, production of fissile material has been treated as by far the greatest danger, and the pace of Iranian production of fissile material has accelerated since 2006. So has the development of missiles of increasing range. What appears to have been suspended is the engineering aimed at the production of warheads.
The NIE holds that Iran may be able to produce enough highly enriched uranium for a nuclear weapon by the end of 2009 and, with increasing confidence, more warheads by the period 2010 to 2015. That is virtually the same timeline as was suggested in the 2005 National Intelligence Estimate. The new estimate does not assess how long it would take to build a warhead, though it treats the availability of fissile material as the principal limiting factor. If there is a significant gap between these two processes, it would be important to be told what it is. Nor are we told how close to developing a warhead Tehran was when it suspended its program or how confident the intelligence community is in its ability to learn when work on warheads has resumed. On the latter point, the new estimate expresses only "moderate" confidence that the suspension has not been lifted already.
It is therefore doubtful that the evidence supports the dramatic language of the summary and, even less so, the broad conclusions drawn in much of the public commentary. For the past three years, the international debate has concentrated on the Iranian effort to enrich uranium by centrifuges, some 3,000 of which are now in operation. The administration has asserted that this represents a decisive step toward Iranian acquisition of nuclear weapons and has urged a policy of maximum pressure. Every permanent member of the U.N. Security Council has supported the request that Iran suspend its uranium enrichment program; the various countries differ on the urgency with which their recommendations should be pressed and in their willingness to impose penalties.
