And consider this: maybe the message won't be heard inside Syria. But it gets coverage outside of Syria. It brings the plight of the Syrian people to the attention of the world, including people who may not otherwise have been paying attention. It could help galvanize calls for action from the international community. It could lead to support protests in other parts of the world, news of which will get through to the Syrian people, telling them that they're not alone.
It could lead to something. That's a hell of a lot better than nothing.
