Plan B: The establishment will attempt to "occupy" Bernie
The establishment had to build a 'plan B' when SYRIZA would take the power. As it happened, SYRIZA was split, losing its most radical elements, which were the real threat for the system, and Tsipras was forced to capitulate with the European Financial Dictatorship, under the big threat of total economic collapse. The European neoliberal establishment declared victory over the people, but paid a huge price, as it has been fully exposed by the financial coup against Greece last summer. The first significant results of these developments can be seen in Portugal and Spain, were the traditional political forces lost much of their power, and the bi-partisan political system actually collapsed. The war in Europe continues.
Similarly, the establishment in the United States may have a 'plan B', in case that Bernie Sanders manage to pass all the way to the US presidency.
