Alyosha .... politically claig is like one of those Russian Dolls, where you open one up and find a new one within, and another, and another.......until find the one with the smallest mind. lol
Re Syriza, they have whipped up an anti EU feeling to such an extent, I can't think what deal that they could realistically bring home and keep the citizens happy - so how many at the end of negotiations will be FIRMLY pro EU/Euro if they don't feel loved or appreciated by the other 18 Eurozone members?
Sundays Referendum was all about ending Greek austerity, effectively a mandate to do what it takes to achieve it.
Whether they go or stay now, Syriza the party has saved political capital/face to fight another day as at least 61% of the voters are with them in this fight, and shit tends to stick to a blanket.
The Greek 'wildcard' is Russia if there really is potential economic help to get then through a Grexit e.g. energy to fulfil their domestic need that doesn't take up finite foreign reserves to pay for it.
You see similar to you, I cannot believe that Syriza has handled this situation so badly WITHOUT an agenda we don't yet know and/or the promise of help if leave the EU.
I usually lean towards leftie economic incompetence over conspiracies, as apparently even here we waited 48-hours before the bank cash point machines ran dry BEFORE rescuing the banks lol, but the way they have handled the EU situation as a very weak negotiator, 'beggars' belief, if there isn't another motive.
