Two of the world's closest military allies are formalizing a shared conviction: that artificial intelligence has moved from the margins of defence planning to its very center. UK leadership, through Andy Burnham, is set to announce a dedicated AI defence partnership with the United States — a deliberate act of strategic alignment that binds London and Washington around a common technological future. In an era when the nature of conflict itself is being rewritten by data, automation, and machine reasoning, this agreement reflects a broader reckoning with what it means to be prepared.
