Zanket, Why? What would they gain? What would we gain from wiping out all chimpanzees? The only reason to wipe us out is if we represented a threat to their survival. I would suggest that something more intelligent than us, by a large margin, would have no need to worry about us. They could easily anticipate and out-think any threat we could imagine. But their actions towards us depend on what objectives they set for themselves. Would they want to become a universal conquering force or would they adopt a live and let live policy? History shows that all conquering forces eventually decline. The more logical approach to long-term survival is to generate friends and not enemies.
