To smooth over Castro’s ruffled feathers; Khrushchev eventually wrote him a personal letter explaining his reasons for reaching an agreement with the United States following the Cuban Missile Crisis. In it, he also extended Castro an invitation to come and visit him in Moscow. The Cuban leader, feeling that this enhanced his international standing, set aside his resentments and swallowed his pride, knowing that his country would have to depend on the USSR for its many needs. He also understood that the ideology that brought his country to where it was had also created many divisions among its people. The United States, on which Cuba had depended on for so many years, was no longer an ally they could trade with, and the new friendship with a distant country created many of its own problems. Many of Cuba’s professional class had fled the country for the United States, when the companies they worked for became nationalized. The brain drain Cuba experienced was hard to replace, and most of those that had stayed, were not prepared to fill the more technical positions. The shelves were bare and people were becoming intolerant of the many domestic problems they were required to face.
