With the Biden administration embarking on its Nuclear Posture Review, it’s time to reexamine the role nuclear weapons play in U.S. national security. While such reviews have become standard when a new team arrives at the White House, President Biden’s comes at a time when key aspects of America’s nuclear forces, such as the Minuteman III intercontinental ballistic missile, are due or past due for replacement or modernization. Although President Trump was a vocal supporter of nuclear modernization programs and even saw a new weapon type deployed and others planned, the current administration and its Democratic allies in Congress are much less enthusiastic.
