The near-certain trader consensus on "No" stems primarily from the absence of any active nuclear weapons development or breakout programs among US allies that could reach completion before 2027, despite ongoing regional security debates. Allies such as South Korea and Japan continue to rely on US extended deterrence commitments, with recent US approvals focused on civilian nuclear cooperation and nuclear-powered submarines rather than weapons acquisition. Legal constraints under the Nuclear Nonproliferation Treaty, technical timelines for enrichment and weaponization, and domestic political hurdles in allied capitals further reinforce the low probability. While public support for independent deterrents has risen in some nations and "friendly proliferation" ideas have surfaced in policy discussions, no ally has initiated the steps needed for rapid weaponization. Late developments that could still shift odds include an abrupt regional crisis prompting emergency NPT withdrawal or covert acceleration, though such scenarios remain constrained by alliance structures and verification challenges.
