John Bolton will resign as U.S. ambassador to the U.N.
Amongst John Bolton's many crimes is his forced ouster of Jose Bustani, the former director-general of the Organization for the Prohibition of Chemical Weapons, a U.N. organ with a role in hunting and regulating WMD in Iraq. Before the war, Bustani advocated solving the perceived Iraq WMD problem through means other than violence; in response, the U.S., led by John Bolton, forced a vote to oust Bustani on trumped-up charges, failed, then threatened to cut funding to the OPCW if it did not have its way, forced another vote, and prevailed. (You can read more about Bustani, and get a full sourcing for his story, by searching "Bustani" at the Mother Jones Iraq War Timeline. After losing his job, Bustani reflected on the saga with Mother Jones.) The U.N. would later rule that Bustani was wrongfully dismissed and award him damages.
Looking for something more recent? According to TPM Muckraker, Bolton's last move as U.N. ambassador was to reject a proposal commemorating the 200th anniversary of the end of the trans-Atlantic slave trade.
So, yeah, good riddance.
Recently, Foreign Policy put together a list of Bolton's most likely replacements. Included are Jim Leach, Republican congressman from Iowa who just lost a reelection bid, Zalmay Khalilzad, ambassador to Iraq and second-tier architect of the Iraq War, and Lincoln Chafee, poor schmo.
