The White House has warned that the United States could immediately stop all aid and assistance to Nigeria if the Nigerian government fails to halt attacks killing Christians — and said it may take action against the militants responsible.

White House spokesperson Karoline Leavitt made the statement during a press briefing, saying: “If the Nigerian government continues to allow the killing of Christians, the United States will immediately stop all aid and assistance to Nigeria and may take action to wipe out the Islamic terrorists who are committing these horrible atrocities.” Her remarks echoed earlier warnings from former President Donald Trump and followed the U.S. designation of Nigeria as a “Country of Particular Concern” on religious freedom.

The comment has further escalated tensions between the two countries: U.S. leaders have in recent days instructed defence planners to prepare options should more direct action be required, while Nigerian officials have strongly rejected claims that violence is state-sponsored or targeted at a single faith. Nigeria has also said it welcomes international cooperation to tackle terrorism — provided national sovereignty is respected. AP News+1

U.S. media and international outlets have covered the exchange widely, noting the rarity of such an ultimatum and the diplomatic sensitivities it raises. Analysts warn the rhetoric could complicate cooperation on security, humanitarian aid and diplomatic engagement even as both sides insist they prefer coordinated action over unilateral measures.
