Now that the election cluster-fuck is over, Greece still has basically two options:
1. Follow the current path of austerity and policy reform.
2. Break from the current path, get kicked out of the euro or leave the euro.
Regardless of what happens, if Greece does anything the powers that be don't want, Greece will literally be on their own. No one, and I mean no one, will purchase 'new' Greek debt. Whatever austerity pains Greece is going through now will be HUGELY worse.
And not for nothing, global banks are capitalized enough to handle a greek euro exit. Greece no longer holds any real cards to re-negotiate.
The markets should know this by now.
