Despite spending decades condemning the UN as the scarlet colored wild beast of Revelation, the Watchtower Bible and Tract Society of New York applied to be a Non-Governmental Organization (NGO) Associate Member of the United Nations Department of Public Information (UN DPI) in 1992, and remained so until 2001.

Such membership is especially hypocritical considering the Organization's history of condemning Christendom for doing so.
