The Obama administration plans to ask Congress to increase spending on the U.S. nuclear arsenal by more than $5 billion over the next five years as part of its strategy to halt the spread of nuclear weapons and eventually rid the world of them.
The administration argues that the boost is needed to ensure that U.S. warheads remain secure and work as designed as the arsenal shrinks and ages nearly 18 years into a moratorium on underground testing and more than two decades after large-scale warhead production ended.
