The greatest, as in LARGE.

Retired general: Iraq invasion was 'strategic disaster';

“The invasion of Iraq I believe will turn out to be the greatest strategic disaster in U.S. history,” said Odom, now a scholar with the Hudson Institute.

Via Juan Cole, who has this comment;

With the Hudson Institute? That is Neocon Central. Now they're supporting Odom to say this?

But his evaluation is correct. The greatest strategic disaster in U.S. history.

Thanks neo-cons! Y'all safe in that raft watching the ship sink? F*ckers.
