Exactly, what to look for in Greece's case? At which stage do you cancel your holiday? Burnings of northern European politicians in effigy, or something more serious?

It's difficult to imagine an EU member state to which I can (almost) hop on a plane without a passport going to pieces like that. Greece seems very much 'one of us', unlike the 'other' that is everywhere East of the Med. Not least their NATO membership. But I'm aware that we blindfold ourselves to stuff we don't want to see until it's too late, and then we all find it terribly inconvenient when we can't get feta and wonder 'how could this have happened?'.

Mediterranean Europe has historically shown a penchant for authoritarian strongmen and authoritarian strongmen generally arise out of economic chaos.

What to watch for, I wonder? Is it as easy for this to happen in this interconnected day and age? Surely it'll be different this time around...

Mmm, UK subject here so I'm a little bit more paranoid about the borderline between illegal activities and speaking about illegal activities.

Also apologies for the double post earlier!

I'm not concerned with discussing things that are illegal but I don't think any of us are interested in facilitating or participating in things that are illegal.

In which jurisdiction? Let's not forget that discussing some things can be illegal in its own right, and not just talking about in 'repressive regimes'.
