From the Executive Summary:

“...[O]ne of the most striking things about these new documents is the degree to which the Biden administration now seems to admit that the ‘hawks’ in the U.S. national security policy community read the strategic environment right after all. This is especially the case where it comes to calling out nuclear weapons threats from great power challengers that make further disarmament progress impossible without dramatic changes in strategic policy by those challengers. ...

“The Biden Administration’s acknowledgment of the dramatically worsening strategic environment, moreover,repudiates much of President Obama’s (and Biden’s own prior) disarmament agenda. The Biden NPR also makes clear that no one should expect further disarmament progress anytime soon, and also that the United States has lost patience with trying to ‘lead’ a world so obviously unwilling to follow it toward such disarmament. If there is to be a chance for resuming post-Cold War progress disarmament, the Biden documents make clear, the burden now lies on China and Russia to turn things around by stopping their escalatory provocations.”
