This week offered a textbook example of not learning from the past. Just before joining the other presidential candidates stampeding to the cattle call of the Iowa State Fair, Jeb Bush laid the blame for the Iraq mess at the feet of... President Obama and Hillary Clinton. According to Bush's foreign policy analysis, it was President Obama's "premature withdrawal" in 2011, after only eight years of war, that created ISIS -- not his brother's decisions to dissolve the Iraqi army, de-Baathify the government, spectacularly fail to create a representative government that included Sunnis, or, of course, invade in the first place. Maybe Bush is auditioning to replace Jon Stewart. Two days later in Iowa, he refused to rule out resuming his brother's torture program. "When you are president, your words matter," he said. Indeed they do. We should take Jeb at his. We can't say he didn't warn us.
