Interesting that the clock started in 1947, the year before Israel became a nation that was "born in a day". In 1949, the clock fell to one of the lowest points it's ever registered due to the Soviet Union testing its first atomic bomb. In 1953, the measure fell to the lowest point since because the United States responded by testing its own nuclear device. The activities surrounding the generation that would witness the fulfillment of all scripture is compelling.
