Why a Southern Hemisphere industrial bloc needed an earlier start

Could Australia, India, and South Africa jointly develop a wartime industrial base rivaling the United States?

Only with a much earlier start; the video's 1939-40 intervention window is too late for that scale of infrastructure.

The proposal pools Australia, India, and South Africa as three major Southern Hemisphere economies capable of supporting wartime production. A program on the suggested scale would have needed to begin much earlier than the episode's 1939-40 intervention window. The timing reinforces a recurring constraint in the video: major industrial infrastructure cannot be improvised on the timetable of an emergency procurement decision. The necessary start date and how closely the combined base might approach American output remain unspecified.
