Final-phase strike preparations
Memorandum 1 · issued 27 Feb 2026, 15:52 UKA high-confidence assessment that actors were in the final phase of preparation for a potential limited initial strike against designated military and security targets in Iran.
Conflict with Iran was widely discussed as possible. The author's account in Before the First Strike is that public commentary was divided on whether it was imminent.
Large-scale US and Israeli strikes on Iranian targets began on 28 February 2026.
The assessment concerned the timing and character of preparations, not whether conflict would ever occur. Its underlying sources are not published, and the characterisation of public commentary is the author's own.
