I'm watching on al Jazeera right now Yassir Abu Hilala saying that the police broke up a big demonstration in support of the Professional Associations, and that the police are preventing the Arab satellite television stations from covering the demonstration. (UPDATE: here's an English story)
This is a small thing, but it points to something which should be extremely worrying to those excited by recent developments in the Arab world. Jordan is demonstrating its mastery of a lesson from Beirut which most analysts have neglected: al Jazeera and the Arab satellites convey power on protestors. Remove the Arab satellite television cameras, and you seriously reduce the power of popular protests. This isn't entirely new - Jordan and other Arab governments have long tried to prevent satellite television stations like al Jazeera from covering such protests - but it is likely to increase now that these regimes feel even more vulnerable. Crackdowns on the Arab media by Arab states are a very likely consequence of recent events.
Here's where American policy over the last few years has been especially counter-productive. As a result of years of Bush administration hostility towards al Jazeera and the Arab satellites - including its sanctioning of the closure of al Jazeera offices in Baghdad and its own hostile rhetoric towards al Jazeera (for details and links, just follow my Arab media archives) - it will be very, very difficult for the US to effectively object when these Arab governments crack down.
