Syriza's stance is to negotiate and not back down. That leaves two outcomes, either the austeritarians fold or they make reality of their threats to kick Greece out of the euro. Either way Greece will again have the freedom to decide their own economic policy.

Given that just leaving the euro is impopular in Greece, I think negotiating hard and looking like you earnestly expect the opponent to fold is the best strategy possible. Like it was designed by someone who is good at game theory.
