I have posted numerous articles on Avaaz in the past (see this, this, this, this, and this), but I still think that this organization needs more light shed on it. Organizations like Avaaz have often been used in "color revolutions" to destabilize countries that refuse to follow orders from the US Empire or to gain a more friendly ally. And such organizations also are meant to seduce well-meaning liberals and leftists to work for them by their appeals to human rights, democracy, and freedom.
Avaaz is, indeed, part of the color revolution apparatus, having apparently received funds from George Soros’ Open Society Foundation to start up in 2007. Avaaz was founded by Res Publica and Moveon.org, both Soros-funded organizations that attempt to co-opt the American left into supporting ideas and campaigns closely associated with the communitarian foundation oligarchs.
