This is why 32 TU 114s were made, 165 TU 124s, 850 TU 134s... Of these planes only the TU114 was international. The Soviets didnt really make a plane until the IL86 came out and there were only 106 made of them (compared to 167 741s, 393 742s during this period) ... They've only made 23 IL-96s.
But, their planes were limited for sale. You had to be an Iron Curtain nation with some few exceptions of Japanese airlines buying some Soviet A/C. Travel was extremely restricted back then. Remember, they were all more or less police states. Heck, a good pair of Denim jeans was considered extremely fashionable there at the time.
Sorry, I could go on. I got my undergraduate degree in Political Science. I had a concentration on US International Security and Eastern Europe/Asian politics.
