Would a Soviet intervention in Suez likely become nuclear war?
Short answerThe answer expects a conventional conflict unless attacks reached the core territory of the nuclear powers.
NotesNuclear use was unlikely unless the conflict expanded to direct attacks on British, French, American, or Soviet homeland territory. Fighting over allied bases, shipping, or Eastern European territory would not automatically cross that threshold. The recent Korean War offered a precedent for severe conventional combat under the nuclear shadow without actual nuclear employment. A hot Suez could therefore become a wide and destructive conventional war while leaders kept nuclear weapons as the final option.
