These are the words (he quotes Sun Tzu words in the article from which I extracted his words):
If you know the enemy and know yourself, you need not fear the result of a hundred battles.... I think we know ourselves AND our enemy in the case of terrorisim this time around (compared to the years X-42 was just 'occupying' the Whitehouse and fiddling while several of our embassies and one US ship were bombed) ...If you know yourself but not the enemy, for every victory gained you will also suffer a defeat.
If you know neither the enemy nor yourself, you will succumb in every battle.[1]
