I said from the beginning 0bama had Stevens taken out. This was our own military acting against a citizen and an ambassador who knew too much.
I've always had a sneaking suspicion that this was an arranged "kidnapping" that went bad when security forces that weren't in on the plan disregarded calls to stand down turned it into a hot firefight.
The theory here is that Obama rides to the rescue to "save" the ambassador while having a pretext for giving his Al Queda buddies more stuff (possibly even the blind Sheik).
