Just an FYI.
Churchill is probably responsible for the Fall of Singapore. His military told him it wasn’t impenetrable and would likely fall in an attack due to lack of equipment and he ignored it. Britain was going to send several hundred tanks and planes out there in 1941 but Churchill sent them to the USSR (who did not want them).
But because people are taught to follow Churchill in a cult like manner, this and his many other catastrophic decisions get ignored.
Plenty of local military incompetence as well. “The Singapore Grip” is a fantastic (and quite funny) novel about the fall of Singapore by JG Farrell.
