It doesn't. That's nto the criticism (or shouldn't be).
Here's how it is described:
1. In Libya, a terror group plans a coordinated assault on the consulate in Benghazi because they perceive the security there to be weak. 9/11 is chosen as the date for symbolic reasons.
2. Independently, and later, imams in Cairo begin complaining about a YouTube video that insults Mohammed. People begin to organize protests. 9/11 is chosen as the date for the same symbolic reasons as the terrorists in Libya chose. But there is no evidence of cooperation between the two groups.
3. On 9/10, the American consulate in Cairo, fearing the Egyptian protests will become violent, issues a statement condemning the YouTube video and calling for calm.
4. On 9/11, the planned protests in Cairo go froward with vandalism and some violence. At the same time, in Libya, the assault kills four Americans, including the Ambassador.
5. Romney condemns the consulate's statement, claiming it shows how the Obama Administration tends to blame Americans for the actions of Islamic radicals, rather than placing the blame on the radicals.
6. The White House states that the Cairo consulate's statement was unauthorized (seen as a weak retraction) and condemns the radicals, the makers of the YouTube video, and also condemns Romney for politicizing the issue.
7. In the Rose Garden, Obama says the attacks in Benghazi were caused by terrorists (true) and made an oblique reference to the YouTube video. (False.) (you can see the Rose Garden remarks
here.*)
8. Subsequently, the US government asks YouTube to remove the video. YouTube refuses.
The issue, in a nutshell, is the GOP claim that the Administration
has a habit of trying to associate a portion of the responsibility for terror attacks to America's own behavior.
