“President Donald Trump reinstated an executive order Monday barring US foreign aid from going to any nongovernmental organization (NGO) that either provides abortion services, or even discusses abortion with its patients as an option for family planning.”

(…)The reality is simple and brutal. Reinstating the global gag rule will not reduce abortions. Sub-Saharan Africa, for instance, had higher abortion rates after George W. Bush reinstated the gag rule, because it reduced women’s access to contraception and caused more unwanted pregnancies, which women then chose to terminate.
