I can't help but think that it ends with the crumbling of Europe as we know it.
- Germany, Austria, etc. accepts this first wave of 120k ppl (or whatever the number is).
- Despite warnings from places like Denmark to not come, the success of the first wave of migrants sends the message that "ppl get asylum."
- This leads to even greater numbers in subsequent waves as the "income inequality" gap between EU and failed African/Arab states is so obvious.
- This scenes play out over and over again at the philosophy of Europe (brotherhood, love, etc.) is put to the test as millions of people who legitimately are looking for safety from Syria, Iraq, Afghanistan, Eritrea, Libya are asking for help.
- If Europe accepts them, there comes a tipping point where the costs of absorption, etc. start to overwhelm the generous social welfare benefits.
- If they don't accept them (or some countries refuse to participate or pay), the EU as an idea of refuge/tolerance starts to crumble.
Either way, it breaks.
This doesn't even include the other, non-PC strain of Islamification of Europe (which would also change Europe).
