It’s still our duty to protect, as we can, our fellow Christians.
We may not be of the world, but we are in it. God doesn’t like suicide, either, and failing to do our best to get the best man in is the equivalent.
I think that furnishing refuge for them should be a paramount consideration in all of Christendom with its various parts.
That would be one reason why we would want a sane America that doesn’t footsie with terrorists.
But there have been no “territory promises” made to Christians. If a territory becomes inhospitable, and staying there makes no sense from an evangelistic point of view, then I’d take that as a sign from God “Move on, My sons and daughters. That may actually make My judgment on the area easier to carry out.”
