The real war on women - Polygamy is legalized in Kenya for men. President Uhuru Kenyatta signed the law on Tuesday legalizing polygamous unions for men. Women in Kenya, however, can only customarily marry one man. Many of Kenya's 42 tribes do not put a limit on the number of wives a man can marry as long as he can afford to do so. Men do not need consent from their current wives if they wish to marry again.
