The carrying out of the Potsdam Agreement has, however, been obstructed by the failure of the Allied Control Council to take the necessary steps to enable the German economy to function as an economic unit.

Summary

This quote suggests that the Potsdam Agreement, which aimed to establish a post-WWII framework for Germany, faced obstacles due to the Allied Control Council's failure to facilitate the functioning of the German economy as a whole. The council's lack of action hindered the implementation of necessary measures required for the country's economic recovery and stability. As a result, the Potsdam Agreement's goals were impeded, potentially prolonging Germany's recovery process and impeding the establishment of a unified and thriving post-war economy.
