So, how to keep the army busy and out of politics? With nearly half a million active soldiers (the 10th largest army in the world, who knew?) they certainly have plenty of personnel. Perhaps if the UN were serious about securing peace in Syria some of these guys could be sent over there, rather than the paltry 300 observers on the last mission. I can't say it's a flawless plan - the Alawites in Syria might be a little worried about letting a largely Sunni force in, for a start. Then again, Syria and Egypt were the same country in the lifetimes of most officers, if not of the grunts. And generals with some proper action on their hands might be less inclined to spend all their time defending their personal fiefdoms.
A pipe dream at best, but given that its clear which side Saudi Arabia is on, it's a more practical solution than asking them to step in and keep the peace.
In a country with such high unemployment, with 3% directly employed by the security services, and no doubt a much higher percentage relying on them as breadwinners, it's worth considering the effect that has both on the national psyche and on politics. Ever wondered who all the goons were who came out in support of Mubarak? A lot of people have a lot riding on the 'deep state'.
