Put simply, the citizens of Western states have lost their appetite for foreign wars; they have lost the hope of scoring any but temporary victories; and they have lost confidence in their way of life. Indeed, they are no longer sure what that way of life requires of them.Like I said, it is the kind of read you need to sit down for. But if you do you'll be rewarded with a thoughtful and, dare I say: shameless defence of the Judeo-Christian values that made our civilization what it is, even as it is nowadays considered distasteful to say such out loud. Pay particular attention to the last two paragraphs of the piece.
If you are in the mood for a slightly heftier read then a mere blog post, head on over to Brussels Journal where Roger Scruton writes about the current state of affairs with regard to the defence of Western Civilisation.
