Islam is a war plan.
I had the odd experience in the late 90’s of having my hair cut in a US military barber shop by a Syrian Christian who had left Syria for Germany. Obviously, this was before the current crisis, but he’d been compelled to leave because of the terrible inequality of dhimmitude, the allowed secondary status of christians enforced by islam. He also shared some odd views on eschatology from his Christian perspective as colored by his experience in that country.
Christians are now being slaughtered. It’s gone far beyond dhimmitude.
If I could 100% ensure that a refugee was a Christian I would absolutely be open to giving that Christian refuge. But without a vetting system, a terrorist would simply have to claim to be a Christian.
A year ago our thoughts on this were not that developed.
The idea of protected zones, safe havens within those lands where the slaughter is taking place, is workable if we had an administration willing to try.
