for a response to the direct question aimed at you about what Bush said he was going to do before invading Iraq, and what he actually did do before invading Iraq.
You didn't respond, but instead responded to a response from another poster, without addressing the original question.
... and hey, I didn't even have to go look at the exchange to figure out what he was talking about; it was a pretty glaring attempt to avoid the issue on your part.
Hence, no credibility; you didn't want to answer because it shows that you're wrong about Bush's willingness to deceive the public, and his willingness to go back on what he said he'd do in the name of expediency.
