Good defense.
Bush is too stupid to be able to tell what all those big words mean (recall he still can't even pronounce nuclear, let alone understand what it means). Hence, he is incapable of lying because he is incapable of understanding what the words in his prepared speech mean. He literally is incapable of knowing whether he is telling a lie or telling the truth.
Even I'd buy that.

The soul and substance of what customarily ranks as patriotism is moral cowardice and always has been...We have thrown away the most valuable asset we had-- the individual's right to oppose both flag and country when he (just he, by himself) believed them to be in the wrong. We have thrown it away; and with it all that was really respectable about that grotesque and laughable word, Patriotism.
- Mark Twain, "Monarchical and Republican Patriotism"
