I'd say that that would be the easy way to be serious, rather than the right way.
There's no doubt we've backslid, but I think if we're being aspirational about what we think the GOC/CAF should do/ should have done I think we should our sights higher than reverting to our pre WW2 place in the world as a vassal- just to a different master.
The problem isn't the mission, it's that the decisions of the last 15-20 years left us in a position where we can't deliver to the tune necessary to live up to our (increasingly former) status as a leading middle power. It's reasonable for us to not be able to field a wholly Canadian division. But a country of our size and means should have been able to step up and be the lead nation of a Multinational Division North that has a wholly Canadian Bde (even if flyover), and a Bn+ manouver component deployed to the MN Bde, + HQ/CS/CSS.
