IF this report is true... we are looking at two embassy attacks that obviously were coordinated and one where it appears they planned on killing a high level target.
Before anyone starts throwing blame around, please remember that the intelligence community will NEVER be able to know EVERY threat or plot out there. What matters now is how we react.
Obviously we don't know how much was known beforehand... but I expect we are scrambling to get all the information now.
From a political standpoint, I certainly hope Romney stays on the sidelines for a while and gives the current administration time to get the facts sorted before making judgments. That being said, you can NOT allow a US Ambassador to be killed without retribution of some kind. This is a complete nightmare.
