Former UN ambassador John Bolton’s assessment of the Bush administration’s Iran policy: naïve, dangerous, clinging to empty notions of diplomacy.

Indeed.

“The current approach of the Europeans and the Americans is not just doomed to failure, but dangerous,” he said. “Dealing with [the Iranians] just gives them what they want, which is more time…

“We have fiddled away four years, in which Europe tried to persuade Iran to give up voluntarily,“ he complained. ”Iran in those four years mastered uranium conversion from solid to gas and now enrichment to weapons grade… We lost four years to feckless European diplomacy and our options are very limited.”

Bolton said flatly that ”diplomacy and sanctions have failed… “[So] we have to look at: 1, overthrowing the regime and getting in a new one that won’t pursue nuclear weapons; 2, a last-resort use of force.”

However, he added a caution as to the viability of the first of those remaining options: While “the regime is more susceptible to overthrow from within than people think,” he said, such a process “may take more time than we have.”

Overall, said Bolton, it was clear that Iran had surmounted “all the technical problems of uranium enrichment,” and it “may well be that we have passed the point of Iran mastering the nuclear fuel cycle.” If so, it was now merely a matter of time before Iran reached a bomb-making capability - “a matter of resources and available equipment,” he said - and it was solely up to Iran to set the pace.

To his dismay, however, the Bush administration was still clinging to the empty notion that the sanctions route could work, “even though [the UN’s sanction] Resolutions 1737 and 1747 were full of loopholes. The US is still seeking another sanctions resolution and Solana is still pursuing diplomacy,” he said bitterly.

Bolton lamented that the Bush administration today was “not the same” as a presumably more robust incarnation three years ago, because of what he said was now the State Department‘s overwhelming dominance of foreign policy.”

“The State Department has adopted the European view [on how to deal with Iran] and other voices have been sidelined,” he said. Secretary of State Condoleezza Rice “is overwhelmingly predominant on foreign policy.”
