Don't feed the doomsayers. The Second Congo War had more interlocking alliances than this.
There's a bit more to be said about media representation of this conflict:
Graun article about disproportionate screentime to Israeli officials here, Atlantic article about I/P sucking up public interest here. I will say that public protest is a very specific measure of dissent, something that I think has a high decay rate. The theory is that protests will likely be ineffective, so once people realize that they move on again. It could also be that the fervour surrounding I/P is maintained by Western nations acting so slowly on it; since western nations blockaded Syria so quickly, there is not much to demand further absent arms funnelling.
