Chemical weapons are evil, but you could also say they’re a curse. They have a talismanic power to bend and distort U.S. foreign policy. You can ask George W. Bush or Barack Obama.
In 2003, then-Deputy Defense Secretary Paul Wolfowitz gave a lengthy interview to Vanity Fair that caused a huge uproar, largely because the magazine shamefully distorted what he was trying to say. Wolfowitz explained that within the Bush administration there were a lot of arguments for why we should invade Iraq. Some had to do with the fact that Saddam Hussein was a state supporter of terrorism. Some had to do with how Saddam treated his own people. Others emphasized alleged links between the regime and 9/11. And so on.
