Thanks for posting that. I was skeptical myself about the claim of "lies".
Real-time intelligence isn't perfect, and things you thought might be true at one point may be proven wrong two years later. That doesn't mean that anyone was deceived intentionally. Also, counter-insurgency wars are notoriously difficult, and ideas/strategies you reasonably believed might succeed sometimes don't. Making a prediction that turns out not to be correct also isn't a lie.
I truly believe we've done the best we can all along. It's just very, very difficult.
