The New York Times, NPR and other major media outlets have already declared the 300-strong UN observer mission in Syria, approved last weekend in the Security Council, a failure. The UN hasn't stopped the violence, or even induced the Syrian government to withdraw heavy weapons from population centers. The observers are unable to protect protesters or ensure that humanitarian relief reaches civilians, as required by Kofi Annan's six-point plan.

All that is true, but premature: As of yesterday, there were only 11 UN observers deployed in Syria. The remaining dozen or so are headquarters and support personnel. Part of the initial contingent came from the UN mission in Lebanon, but the Secretary General will not want to denude that effort to staff Syria. It will take time to get UN member states to cough up more troops for what is obviously a dangerous effort.

The press reports that violence typically subsides when the observers are present but surges once they leave. To journalists, this is a sign of their ineffectiveness. To diplomats, it means that they may be able to tamp down the violence, provided they are deployed in sufficient numbers.

If the 12 already deployed work in groups of at least three, they can be present in only four places on any given day, provided they have adequate transport, which is not ensured. Of course they haven't been effective yet. They haven't really arrived. The remaining several hundred will take weeks, maybe even months, to deploy.
