The Nigerianmilitary has increased cooperation with the US in efforts to combat extremist violence (file photo). Nigeria's President Bola Tinubu has confirmed the killing ofa senior Islamic State (IS) leader in a joint-operation with the US. Nigerian officials visited the UnitedStates, while the US sent fact-finding missions to Nigeria. In what seemed like a positive move, the U.S and the Nigerian government agreed to work together. Operation FANSAN YAMMA, the military campaign responsible for airoperations in the northwest, confirmed carrying out an airstrike in the area. However, the military's account of what was hit diverges sharply from what survivors and rights groups describe. The dataset reveals that the UnitedStates pursued a remarkable number of regime changes during the Cold War (1947–89) and that the vast majority of these interventions were conducted covertly—sixty-four covert interven-tions compared to six overt ones. Nigeria has recorded several incidents of accidental airstrikes on civilians during militaryoperations over the years, resulting in significant loss of lives. On March 16, 2014, a misfired airstriketargeting terrorists in Kayamla village, Borno State, killed at least 10 civilians. The UnitedStates has deployed a small team of troops to Nigeria following Christmas Day airstrikes, marking the first public confirmation ofaU.S. military presence on Nigerian soil since the operation. The CIA and the U.S. military’s Joint Special Operations Command (JSOC) operate parallel drone-based assassination programs, and the secret documents should be viewed in the context ofan intense internal turf war over which entity should have supremacy in those operations. UnitedStates conducted airstrikes on three key nuclear sites in Iran.
