Western Politicians will NEVER do that. Instead Behaving like a bunch of traitors.
They know they need to do something. But I suspect that also know that by reversing it, the consequences are beyond what they can comprehend. Even back in 2012 the likes of Merkel was saying how the model was simply not valid anymore.
And the choice about whether they keep it or not will not be made by a vote. It will be foisted upon them simply by dint of the money running out. You cannot pay out what you don't have.
Now does the nation state, in the form we all just accept as 'normality' survive it? I don't know. But the choice for the West is simple. We either become an Islamic civilisation or we remain a Christian one. The secular version is imploding. Only question is if enough Ethno-Europeans wake up in time to understand this.
