The idea that a country would be surprised and shocked to find out that other countries - including allies - had plans in place for military operations against them is ludicrous. Every country's military war-games potential conflicts, even when they're far less likely to ever be used than plans for Britain ending up in conflict with the USSR after the end of WWII. Those plans weren't even approved lol, Churchill was out of office shortly after ordering that plans be drawn up.
