I'm no political blogger, but I do take a mild interest in the blunderings of George W. Bush for pure entertainment value and just in case he accidentally presses the big red button when he's meaning to call for a pizza. Today I stumbled upon a Huffington Post article quoting Dubya's recent speech about the latest developments in Iraq:
War critics can no longer credibly argue that we are losing in Iraq, so now they argue the war costs too much.” President Bush - March 19, 2008.
As you can see from the second part of the sentence, Bush is trying to attack the methods of war critics. I include that just for context, but it is of no importance to the following point.
Taking just the first part of the sentence, Bush is clearly saying that up until now there has been credibility to the argument that the US Army is losing in Iraq. Which to me reads as an admission that each time he's assured the world of their success for the last four years, he knew it was a lie.
The Huffington Post has the man's incompetence in full.
