Your opposite number in a negotiation might have to put on a show to look tough for his backers. It doesn't mean the deal is over. This is what he has to do to keep it on track.

It took Morsi two days to call on Egyptians to respect the inviolability of foreign embassies.
The Muslim Brotherhood issued a mealy-mouthed statement that condemned violence, but also justified the violence as a response to the insult of the prophet, which one of the group’s administrators labeled a “red line.”
But it would be wrong to think that Morsi or the Brotherhood want these protests.
Morsi is trying to cement a $4.8 billion loan from the International Monetary Fund to stave off economic collapse.
The Brotherhood is trying to drum up investment in Egypt (lest it be held accountable at the polls for a collapse).
Attacks on the U.S. embassy do not help their cause.
These protests, like all protests, are organized by political actors with agendas.First, and most obviously, are other Islamists.
Staging protests against the United States is a way of showing up the Brotherhood, of saying that the group is too weak or corrupted by power to do anything to protect Islam’s honor.
If Morsi condemns the protests, he can be portrayed as a hypocrite who talks tough about the West but in reality is willing to make himself its lackey in order to hang onto power.
