I think that if it's a probability, there's only a very, very narrow chance of us getting a question on this, or even "whole historiography on haig and the individual wars". In peace movements, they will only ask about it generally; things like the Stockholm Conference would only be needed to support your answer, but you could just refer to supports that are much easier to remember [and more relevant].
I'm not studying the historiography on Haig and the battles either [except generally for the battles]. I reckon doing all that is a waste of time, [but then again, if I'm wrong, you're getting the marks.]
The international studies is a waste of time... 80-90% of what we study will be useless for the HSC... One question on one freaking dot point. pfft.
