Gennadiy N. Lepeshkin: We were all raised with the strict notion that we had an adversary and that we should prepare for some sort of attack. The entire Soviet people had this instilled in them. And this was how we perceived the very first foreigners who came to see us--they were, essentially, colleagues in the work that I was doing. When the delegation came to see me, I invited them into my office, we introduced ourselves and they explained the purpose of their visit, and I said, "Well, dear comrades, I haven't received any instructions regarding your visit, so I'm going to provide you with a vehicle and see to it that you have a tour of the city, restaurant meals and a hotel stay. When I receive instructions to allow you onto the site, then I will arrange for you to come. By the time they left two days later, we had become fast friends.
