Eaton writes that an impressive aspect of the Pugwash Conference was the Soviet scientists. "Not only did they demonstrate that they fully equal their colleagues from other countries as specialists in their fields, but they also consistently displayed a considerably broader knowledge of activities within the governments and military establishments of their own and other countries in both East and West. The Russians are obviously working hard to make the most of this world, and leaving to others preoccupation with the theoretical benefits of the world to come."

A disappointment of the Conference was that "more than a few" of the Continuing Committee members were unable to attend.
