I don't think there is much to add to what Dan Froomkin notices:
The White House issued a solemn statement Thursday commemorating the sixth anniversary of the al Qaeda attack on the USS Cole.
The White House has been citing the Cole a lot lately, as part of its narrative that President Clinton, who was in charge back then, was asleep at the switch when it came to terrorism.
I went back to see what the White House statement was like on the fifth anniversary of the attack on the Cole. But there wasn't one!
And there wasn't one on the fourth, the third, the second or the first, either.
