You need to read the entire article, but the conclusion is quite good:
The week began with an old soldier running Egypt. It ended with different old soldiers running Egypt with even more formal power than Mubarak had. This has caused worldwide shock and awe. We were killjoys in 2009, when we said the Iranian revolution wasn’t going anywhere. We do not want to be killjoys now, since everyone is so excited and happy. But we should point out that, in spite of the crowds, nothing much has really happened yet in Egypt. It doesn’t mean that it won’t, but it hasn’t yet.
An 82-year-old man has been thrown out of office, and his son will not be president. The constitution and parliament are gone and a military junta is in charge. The rest is speculation.
I like everyone's idealism, but the facts are the facts....
