"That American soldier wasn't born, the spy thriller he's reading wasn't written, and we both thought the Wall would he demolished within a few days. We were stupid kids but it was better then, wasn't it, Bernie?"
I really like this line. I think that these ideas Deighton mentions were about the time before Soviet and European/American tensions began. Spies were not well known yet, in some ways the modern American soldier was coming about, and as the Werner mentions, the Wall was expected to only last a few days. This shows how many "kids" had to grow up faster than expected because of these tensions and because these countries were on the verge of war.
