Donald Rumsfeld doubles down on the downplayer when he both uses the ‘so-called’ qualifier and marks the usage with tone when he characterizes President Obama’s role as Commander in Chief (video HERE):

Downplayer? Check. Modus tonens? Check.  Answers about whether the reasons for the Iraq invasion were worse or better than Obama’s reasons for Syria? Whoops.
