Where did you see evidence of bad communications between agencies? It appears that all relevant agencies were working from the same data at the same time. This is NOT the first time something bad has happened. State, Defense, CIA, NSA, and the White House all had the same information. None of it pointed to a protest over a video.
The president said as soon as he heard he told Defense (Panetta?) to make sure those people were safe. Here is a quote from the president, "“Well, we are finding out exactly what happened,” the president again said. “I can tell you, as I’ve said over the last couple of months since this happened, the minute I found out what was happening, I gave three very clear directives. Number one, make sure that we are securing our personnel and doing whatever we need to. Number two, we’re going to investigate exactly what happened so that it doesn’t happen again. Number three, find out who did this so we can bring them to justice. And I guarantee you that everyone in the state department, our military, the CIA, you name it, had number one priority making sure that people were safe. "
The president debunks your claim of bad communications. It was clear to him, according to his quote, that he knew Americans were in danger. There were many other indicators, almost immediately, that everyone in WADC, was getting information as the attack was ongoing.
What resources were strained? We had an unarmed drone (Predator?) overhead providing video. Given all that had occurred in Libya I am confidant we had lots of other intelligence gathered before, during, and after the attack.
This attack lasted roughly seven hours. Confusion is for amateurs. It lasts for just a few minutes. Not seven hours.
Your arguments ring hollow. And your link agrees with my assessment.
So what is the regime hiding?
