My guess is they will rely on their comrades in the LSM to never let the story see the light of day.
It is fun in a perverse way to watch them twist to cover all of their deceit though.
The only reason I say perverse is because the stakes are so high, other wise it would be just plain hilarious to watch them implode.
I suspect they are already doing conferencing-calls with the LSM heads to get their stories straight for when the Syria WMDs become a story.
No doubt the toppling of Assad will be postponed until they feel confident their strategy is fixed.
