Sen. Barack Obama, D-IL, went on the attack today in a sharply worded editorial on the Lieberman-Kyl Iran Amendment that graced the pages of the New Hampshire Union-Leader. There were two targets of the Senator's ire: the first was the amendment itself, which accuses Iran of fighting "a proxy war against the Iraqi state and coalition forces in Iraq" and designates the Iranian Revolutionary Guard a terrorist organization. The second was Sen. Hillary Clinton, D-NY, for her vote in favor of the measure.Obama charges that the amendment has "opened the door" to military action with Iran, and calls out Clinton as "the only Democratic presidential candidate to support this reckless amendment." He continues: "We do need to tighten sanctions on the Iranian regime... But this must be done separately from any unnecessary saber-rattling... Above all, it must be done through tough and direct diplomacy with Iran, which I have supported, and which Sen. Clinton has called 'naive and irresponsible.'"Despite his condemnation for Lieberman-Kyl, Obama didn't vote against it. He didn't vote at all. Both he and Sen. John McCain, R-AZ, were on the campaign trail when Majority Leader Harry Reid allowed the amendment to hit the Senate floor (on relatively short notice).
