I think the first goal of the entire EU establishment will be to scare voters off Syriza, and whatever they'll say won't really equate to (is probably worse than) their post-election contingency plan. If Syriza wins, the second goal will be to scare off potential coalition partners from joining them for a viable government majority. If that fails, there is still the option for some compromise in which Greece gets some debt relief and EU leaders [here I mean both leaders of EU institutions and EU nation states] can claim that Greece can leave the bailout regime because of the good work of the previous government. Making an example will come if the confrontation reaches points of no return from the EU elite's view like Greece leaving the Euro.
