Much the same situation exists in the Third World where the borders of Islam meet the non-Islamic world. Places like Nigeria, India, and Malaysia have long had mixed communities where Christians and Muslims have lived in relative peace despite some horrible exceptions. The last twenty-five years have seen a rise in violence; however, as, usually but not always, Muslims have targeted the Christians.
One variable in this violence equation, Islamist Extremism, has been explored ad nauseum. Another factor exists though: the rise of an active and confident Christianity that is not based in London or Rome but instead is primarily a local affair even if it is Anglican or Catholic. Religious expert Philip Jenkins explains that this Global South Christianity believes in its teachings, relates to the stories of the persecuted poor, and has a joyful energy in spreading that I feel has not been seen since the Jesuits converted North and South America.
Already Global South Christianity has deeply impacted the United Methodist Church and the Anglican Communion. Protestant Global Southers are becoming more active in missionary activity in Africa and even the First World. Catholic Global Southers in Africa are getting the Church more active in social issues while remaining conservative in theology, thus avoiding the trap of Marxism that Latin American Liberation Theology Catholics fell into it.
Global South Christianity will continue to grow in power in both the Third and First Worlds. I except that in a few decades theologians from Africa and Asia will been to weld great sway in Global Christianity.
