This event scores low on constitutional damage (A=5.05) despite international scope modifier because the mechanism is vague and lacks concrete policy details. The 'policy_change' mechanism is asserted but not substantiated with specific actions, treaties, or legislative changes. Election driver scores 3 due to potential foreign policy implications, separation scores 3 for executive foreign policy shifts, but other drivers remain low without evidence of institutional damage. B-score is moderate (14.39) with media-friendly framing and narrative pivot potential around US retreat/UK expansion themes, but lacks viral characteristics. The single-source nature, absence of verifiable policy documents, and vague 'pulls back' language trigger noise flags. This appears to be speculative reporting or early-stage diplomatic positioning rather than concrete constitutional impact.
