The press is again full of reports that the troika (IMF, EU, and ECB) have reached an agreement on Greece. Markets will again rise, until they see that little has happened.
The troika has agreed to release a new tranche of rescue funds to stave off a March Greek default. Private lenders have agreed to their haircut (but that had really been decided a long time ago). The rescue funds will probably be doled out slowly to make sure that Greece meets its end of the bargain and cuts wages and public sector employment.
With an election coming up (and the public vehemently against outside intervention and austerity), Greece cannot meet its end of the bargain. Greece can only do so by agreeing to be governed by external bodies, such as the troika, which spells the end (temporarily perhaps) of Greece independence.
This is one of a hundred of steps that remain to be taken before we can say that Greece has been rescued.
