The Yemeni Civil War makes it appear as if there is very little involvement from the three global superpowers, while the Syrian standoff was worryingly similar to a cold war era proxy war. Also quite close to Europe, thus more important for our media and upcoming elections.

Though with the Syrian conflict dying down, I'd expect others like Yemen to get more attention by filling the "war" slot in media.

Not that I totally disagree with the gist of your comments, but the Syria situation seems much more relevant internationally, with Syria involving direct military actions in of two world powers and a NATO member. Not to say that any of the attrocities are to be ignored...
