The reality is that Greece is facing a tought time with the current economic crisis, but this is not a problem that is exclusive to Hellas. Portugal, Ireland, Spain and other countries, including Italy are in a similar situation so this is not, in my opinion, the right time for PASOK members to be searching for a new leader for the party.
The decision to go for a national government of unity was a reasonably good one and no one should blame George Papandreou for the few mistakes he made prior to that decision. The fact is that external forces have forced the country to take the current steps but the reality is that these forces can not be ignored and we have to work with what we have even though it hurts. Better times will come and with that more worthy leaders?
