Something often missed is that hypothetical discussions such as these lead to participants recalling detail and references to what really happened and the various inputs into the actual decisions made. I refer back to this topic because of some of the excellent references provided by JFC Fuller on the Henderson and Jellico reports.
The thing with historical hypotheticals is often people at the time put forward the same or similar ideas for the same or similar reasons but lost the argument. Something I have seen in my own lifetime was three failed attempts to get OPV / Corvette sized minor combatants for the RAN, the first killed by scope creep and a change in government, the second and third by changes of government, before the party that cancelled them was in power long enough to feel the pain of having gone for a "cheap" patrol boat instead of an OPV, then finally realised that the OPV hull was also good for replacing capability in other areas, Hydrographics, Oceanography and MCM, i.e. exactly the scope of the project they killed several years (and billions of dollars wasted) earlier.
I bring this up because many of the economic and political arguments brought up on historical discussions are the same as those used in the OPV / Corvette saga. The winning arguments of cost and need, accusations of gold plating and economic irresponsibility etc, were shown to flawed, if not totally false. Why? Because we have come full circle and are finally building the ships (or closer to the ships) that it was determined that our geography and economic requirements needed in the 60s, 70s, 90s and 2000s, that previously have been cancelled in favour of poorer options that were unfit for the role and had to be supported by major fleet units, resulting in waste, wear and tear, and poor performance.
