The "Palin doesn't know Africa is a continent" turns out to be a lie. But it should remind us that the anti-war left were in fact the ones who didn't understand basic geography of Africa. In his State of the Union speech in January of 2003, President Bush talked about aspects of Saddam Hussein's WMD programs and stated that the Iraqi dictator had "sought quantities of uranium in Africa." Somehow, this generated a boondogle investigation by Joe Wilson to the country of Niger the following summer, after which he pronounced in a July 2003 op-ed piece in the NYT that Bush was wrong about an Iraq-Africa uranium connection.
That a former US Ambassador could possibly provide an assessment about an entire continent based on a visit to one country on that huge land mass is mind-boggling.
Perhaps the people who are really geographically challenged are our astute ambassadors and intelligence "operatives" like Valerie Plame; or maybe they simply misled the American people about Iraq's WMD. Hint: likely both of these are equally valid.
