I think that I've come to the conclusion that:
Treaty of Versailles (1918) + Warsaw Pact invasion of Czechoslovakia (1968) = The Economic Conditions Imposed by the Troika on Greece (2015)

When you have the Troika impose conditions, which are backed by countries which also have had austerity imposed on them (like Latvia and Ireland), then the conditions can't be great. The Greek Government now effectively has zero control over it's own Fiscal or Monetary Policy and is still expected to achieve something.

Basically Greece is cussed beyond all cussing cuss and is totally cussed.
