The Pentagon is reportedly drafting a new nuclear strategy intended to give President Donald Trump more options for using shorter-range nuclear weapons during a regional conflict involving China or Russia. The move matters because it could shift US nuclear planning towards more flexible, limited-use scenarios, potentially affecting deterrence and the risks of escalation between major nuclear powers.

The classified effort is reportedly being led by Elbridge Colby, the Under Secretary of War for Policy. It would place greater emphasis on tactical nuclear weapons, which are designed for shorter-range battlefield or regional use rather than large-scale strategic attacks.
