Joseph McCarthy, the Senator, who led the witch-hunts against communists in the USA between 1950 and 1954 at the start of the Cold War was born 14 November 1908 3pm Grand Chute, Wisconsin.
He had an intense, obsessive 8th house Scorpio Sun. And more significantly had the Uranus opposition Neptune of the time on his MC/IC axis. There is an irrationally fanatical side to Uranus Neptune which he clearly lived out. This opposition squared onto Mars Venus in Libra, making him verbally combative and emotionally erratic. Plus his Mars was in an enraged, can-be-brutal trine to Pluto.
When he started his high-profile campaign to root out reds under the bed, Saturn had just moved into Libra and the Uranus square Neptune was at its height through his four-year terror regime. When it started to wane he was removed from his position.
The only similar thing at the moment is tr Uranus moving to hard aspect the USA 1776 Mercury in Cancer opposition Pluto in Capricorn in 2017/18 but it lacks to highly-strung Neptune connection.
The Tunisian terrorist being sought in connection with the Berlin Market killings, was born 23 December 1993 (Tunivision). If accurate, this gives him a close Uranus Neptune conjunction.
