The Far East war and the limits of 'betrayal' narratives

Is the argument that Britain betrayed Australia before the Pacific war persuasive?

He finds the argument incomplete because European war arrived in the wrong order for British planning and neither Britain nor the Dominions had built enough forces to meet every demand at once.

Some 'great betrayal' accounts of British and Australian policy understate the strategic sequence Britain expected. British planning assumed Japan would be the earlier danger, followed by Italy and only then Germany. Instead Germany and Italy created the European crisis first, pulling equipment and effort westward before Japan entered the war. Britain could not replace ships and matériel quickly enough to meet every theatre at once, while Dominion naval expansion in the interwar years had also lagged behind the demands later placed upon it. This interpretation does not erase Australian grievances, but it reframes the failure as a mismatch between expected war order, production capacity, and collective preparation.
