The head of the Pentagon's Defense Intelligence Agency (DIA) has been dismissed by the U.S. Secretary of Defense, marking the latest disruption in U.S. military and intelligence leadership. While the official reason for the firing remains undisclosed, reports suggest that the decision followed disagreements over an intelligence assessment related to potential attacks on Iranian nuclear facilities. Senator Mark Warner, the top Democrat on the Senate intelligence committee, criticized the move as an example of politicizing intelligence under President Donald Trump's administration, describing it as using intelligence as a loyalty test. This dismissal occurs amid ongoing tensions within the U.S. defense and intelligence communities.
