I also believe that you can't underestimate the problem of Greece's eastern borders. The need for constant purchase of arms has only reinforced the kleptocracies that grew on rubble in the 1950s. Marshall Plan aid came in the form of subsidies for arms purchases. Then you got Cyprus and the falling out with the USA, followed by Greece's deliberate move toward non-aligned countries in the 1980s, the institution of a market economy for the first time 25 years ago, to the 1990s when the economy began to grow.
