Oswald’s reentry into the United States was absurdly easy, considering his treasonous track record. He had tried to renounce his citizenship; he had declared his intention to betray his country by handing over some of its most zealously guarded military secrets; he had lived as if he were a Soviet citizen for well over two years. And to top it off, he was bringing back with him a Russian wife, Marina, who had been raised by an uncle who was a KGB officer.
