It might help in many ways, but the basic problem is still there. Religious extremism is a symptom, not a cause. There is an underlying, primal problem with humans - we have evolved to function in groups and compete with other groups for resources. Just like many other primates. Even without the issue of Christianity vs. Islam, the middle east still has plenty of potential for violence and horror. When a weaker group possesses natural resources that a powerful group really wants, you hardly need a religious excuse for conflict (although the religious element simply makes it that much worse). Even without religion, there are crazy, powerful individuals in North Korea that could potentially start a nuclear crisis. The cold war, which could quite possibly have come to a very ugly end for all of us, was largely a secular issue.
There has not been an evolutionary reason for us to want to all get along nicely, unfortunately. It would be more rational, but we are not primarily rational creatures, at least in terms of numbers. Greed and power-lust and other basic urges are still stronger forces, it seems. Even without religion, we'd keep killing each other. The seeds were planted and the killing begun long before anyone thought up Jehovah or Allah.
