I have often heard the expression "the battles of academia are so long and bloody because the matter so little".
Perhaps that is ultimately the problem here - It just doesn't matter.
You're probably right on that. It certainly seems clear that as early as the 50's the leaders of the Army/CF seriously questioned the need for the Militia at all. A repeated theme in the book is that both military and civilian leaders really question the need for the Militia at all, beyond a vague political purpose.
Large scale mobilization has been almost universally seen as being a non-starter ever since the USSR got the bomb. Any war between nuclear powers would be over (either escalated to nuclear war or negotiated to prevent nuclear war) long before any mobilized troops would have the ability to take part in the conflict. Besides that there has simply never been the capability to rapidly deploy or even equip said mobilized forces.
In the case of a non-superpower, or regional proxy conflict, the view seems to have been that there would never be mobilization of Reserve units and that their only role would be individual augmentation. Even in this case the Reserves were seen as preferably used to augment domestic Reg Force positions in order to allow those Regulars to deploy as opposed to direct augmentation by Reservists.
It seems to me that our (military and political leadership's) self-delusion about what the CF is REALLY capable of doing results in a Militia (and Reg Force) structure that is simply far too bloated and inefficient. Ironically, accepting a reduced (in size anyway) role for the CF would likely be something that would be politically sellable to the majority of Canadians while at the same time the resulting, leaner and realistically organized military could hopefully be more efficient and reasonably well equipped.
Hamiltongs: I don't think anyone is saying that Reservists are "bags of hammers"....just that the Militia as an organization is structurally designed to fulfill a role (fully trained individual augmentation) for which they are really not well suited, or alternately a role for which there may be no real need and/or ability to support (massive mobilization). There are always individuals that make liars out of any generalization, however, and of course many Reservists played a key role in Afghanistan. The question though is whether the Militia as currently designed is the best way to fulfill this role.
