It is certain that various US think tanks will be monitoring right now the rise of the Left in Greece with the radical-Left party SYRIZA, as well as Podemos in Spain and other countries in Europe.
It's quite remarkable that the US political system, especially after Clinton administration, has been adopted by Europe, with the transformation of the Social-democrats. A characteristic example is Greece, as the Socialist party PASOK under Kostas Simitis, implemented the neoliberal perception of the free market and the financialization of nearly every aspect of economic activity.
However, as in the US the Left was demonized for decades and totally vanished from the political scene, Europe was meant to be the field of the new Leftist political powers, after the latest global financial crisis. Inevitably, any possible change will start from Europe and follow a reverse direction of that of neoliberalism in the early 90s.
