Here is another worthy interpretation of the dramatic turn-about by the Syriza party in Greece when they submitted to European Union's demands.
This means, first of all, understanding the nature of Syriza and its political co-thinkers, which the WSWS has defined as “pseudo-left.” The actions taken by Tsipras flow inexorably from the class basis of Syriza, a bourgeois party resting on more privileged layers of the upper-middle class. Syriza could not resist the demands of the European banks, because to do so would require mobilizing the working class against the national bourgeoisie within Greece itself, which functions as a fifth column of European imperialism.
