Overview
- General David Petraeus, speaking to the House of Lords on 1 September, urged the United Kingdom to reorganise its defence institutions and take the lead in reshaping NATO around lessons from the war in Ukraine.
- He described Ukraine as the defining military laboratory of the twenty‑first century where sensors, software, unmanned systems, electronic warfare and precision strike are being fused to change how battles are fought.
- Petraeus warned the United States still lacks a new concept of warfare and said buying advanced technology alone will not work without changes to force structure, training, leader education and procurement systems.
- He cautioned that removing the human‑pilot constraint could enable large autonomous drone swarms for which Western defences are currently inadequate and urged faster doctrinal and air‑defence adaptation.
- Petraeus called for NATO to agree on a common concept of warfare to guide reforms, while warning that political and industrial resistance could slow change and leave Western forces at a lasting disadvantage.
