So far, it seems headed to a civil war anyways...
So, which country you are suggesting should be so selfless to take part in a civil war that has nothing to do w/ its own interests? If anything, it's remarkable, how forceful the international community has been, which gives hope the usurper is going to be ousted. Compare this w/ what happened, say, in Iran or Belarus recently.
There is one big difference between Ivory Coast and Iran or Belarus : that is, power. The cowardice of diplomats grows exponentially with the military/diplomatic/economic power of the country they have to deal with. Iran is a major regional force, could soon have nuclear weapons and supports islamist movements throughout the Middle East. Belarus has the support of Russia, a nuclear power and key provider of oil and gas. So they are free to do whatever they want. Ivory Coast is also (so far) more or less free to do whatever it wants, but the reason some people have the courage to stand against the most blatant offenses to democracy is merely because it's a powerless country.
Basically, the international community works like a jungle. You are strong, everybody respects you. You are weak, people treat you as they wish.
