"I wonder if the soldier on the right wasn't shot dead or sent to Siberia soon after having taken this picture."
lizol--taking pictures with American soldiers at the end of WWII was a perfect propaganda for USSR. It's not something to get shot for. There were plenty of other reasons to be sent to GULAG or get shot (i.e. being POW in Germany and Nazi Occupied Europe, being surrounded by enemy troops and break through the encirclement). There was no need to have another reason to get shot or sent to GULAG for taking pictures with Americans.
