Force Z and the accumulated consequences of earlier decisions

The argument links Britain's limited options in 1941 with the shipbuilding decisions of 1939. Earlier carrier availability might have increased the damage inflicted on the Italian fleet and reduced the force needed in the Mediterranean. With fewer Italian battleships available, convoy actions would more often pit cruisers against cruisers, making those encounters more evenly matched. The argument then considers further consequences for Crete and for moving British ships into the Indian Ocean. Each stage depends on the preceding counterfactual outcome, so the whole chain remains conditional. Japan is described as having the world's third-largest navy, making a small display of British capability an unconvincing means of intimidation in this assessment. The preferred use of the available ships is a concentration around Ceylon.
