Angst over China, Russia lessens chance of U.S. nuke changes

Major shifts in U.S. nuclear weapons policy seem unlikely, and while U.S. President Joe Biden may insist on certain adjustments, momentum toward a historic departure from the Trump administration's policy appears to have stalled.

Then China happened -- revelations about its expanding nuclear force and talk of potential war with Taiwan.

And then Russia happened -- signs that it might be preparing to invade Ukraine.

Now, major shifts in U.S. nuclear weapons policy seem much less likely, and while Biden may insist on certain adjustments, momentum toward a historic departure from the Trump administration's policy appears to have stalled.

The outlook will be clearer when the Biden administration completes its so-called nuclear posture review -- an internal relook at the numbers, kinds and purposes of weapons in the nuclear arsenal, as well as the policies that govern their potential use. The results could be made public as early as January.
