Chemical Red Lines on Syria - By Paul R. Williams, J. Trevor Ulbrick, and Jonathan Worboys | The Middle East Channel
This blog explains better what I've been getting at;
by drawing an explicit red line around the use of CBW, the United States has implicitly signaled that it would not intervene otherwise, potentially emboldening the Assad regime. Indeed, since these red lines were established in August, the Assad regime has shown little restraint, attacking civilian areas with indiscriminate weapons such as cluster bombs, artillery, and helicopter gunships.
Like I said, why wait? Obama's worried he'll be compared to Bush? Not buying that, in some ways he's already been to places Bush never did.
