A new report by the Pakistani government cites "gross negligence" for allowing the al-Qaida leader to hide out so long. It has been a source of contention between the United States and Pakistan since the 2011 raid in which Navy SEALs killed Osama bin Laden: How could the world's most wanted fugitive hide in a country that was supposed to be committed to catching him? The relationship between the two nations was sour before the raid—U.S. authorities didn't notify Pakistan about the bin Laden raid for fear of alerting the target—and the humiliation of the armed action damaged the relationship even further.
