Whether or not WWIII will be a war between Christianity and Islam or between China and the Western world, there is little hope that we can remain neutral or otherwise escape the conflict.
Our close proximity to China and Taiwan will likely draw us into a conflict if it erupts in the region. OTOH, if its a "clash of civilizations," as some people are calling the brewing conflict in the Middle East, we still won't be spared since we have large populations of both Muslims and Christians on our own soil.
That's why we should redouble our efforts to pray and work for the maintenance of peace in our lifetimes.
