well if there is a LoN/Collective secuirty question, I wouldnt say i'd concentrate on nazi FP, because you have to look at the dot points: abyssnia and the spanish civil war.....Germany was not a member of the LoN at this stage ( i think - clarification?), and so you wouldnt be looking at nazi foreign policy for the collapse of collective security in terms of the failure of the leage.....For collapse of security i'd defo look at abyssnia, spanish civil war AND THEN, maybe anaylyse the FP like rearmament, re-occ f rhineland, sudetenland...but nazi foreign policy is more to do with the policy of the appeasement, rather than collective security (since col.sec. is a part of the LoN dot point - Germany wasnt in the league then)
