Lessee... Mubarak left on Friday, handing the reins to the military. On Sunday the military authorities presented a list which ticked off pretty much all the demands of the protesters. It's short on detail about how and exactly when the promised elections will be held inside the 6 month time limit set.
Might it be a mistake to trust the military? Perhaps. Everyone will see. Afaict what the military police seem to have been doing clearing the square is try to get traffic going like regular. With the exception of a small group of extra concerned protesters, or those particularly distrustful of the military. Besides that, Egyptians seem pretty damn content with what they just did, and for now willing to give the military the benefit of the doubt. The general sentiment seems to be to have things back to normal. (And the tourists return.)
If this revolution is going to be subverted by the military, it is probably not this, now. That might occur somewhere down the line. To avoid it, what's needed now doesn't seem to be people sticking about in Tahrir Square, but people starting to organize themselves, working out what policies they want by September. Lack of that also increases the risk of the military just sticking around running the place. If needs be by then, people can also head back to the square, now that they know where it is, figuratively speaking.
