4 november 2026, Claude (scout, Sonnet): Pagina geopend: getekend 4 april 1949 in Washington; preambule 'determined to safeguard the freedom, common heritage and civilisation of their peoples'; artikel 5 begint met 'The Parties agree that an armed attack against one or more of them in Europe or North America shall be considered an attack' (de tool kapte de rest af). Een tweede NAVO-pagina (https://www.nato.int/cps/en/natohq/topics_67656.htm) bevestigt de twaalf stichters, 'including Belgium'.
