As in Nazi Germany the average person was apathetic, the devious and ruthless will win the day. That’s why we could very well see Golden Dawn win power in Greece. And then all bets are off.
Actually, I don’t know what’s worse for Greece. Ideally, they have a “vivid” debate on re-population by other cultures. But in reality, they will simply jail the side that has a problem with re-population.
So it leaves it to people that have nothing to lose, and that results in violence and lots a bloodshed.
But the alternative...becoming like Lebanon in the 1980s (a fairly even mix of Muslims and Christians), and then descending from there to be a Muslim-only state - that also doesn’t sound to good.
But, most likely, the new majority there will simply invite Turkey in and ask to be a province. And then Greece, as it has been know for millennia, will simply CEASE TO EXIST.
