I think, most people would agree that is unreasonably low
One needn't be particularly attuned to all things military in such an assessment, as I don't think any hospital or power company or business would think 58% ready to accomplish our goals or meet our needs would be reasonable.
That said, virtually no organization runs at 100% optimal capacity at any given time.
What would be a fair number here? It is 85%? 90%? etc.
These are commitments we make to our allies. NATO is counting on us meeting 100% of our commitments. Any less and deterrence for the alliance as a whole suffers. This is akin to saying what level of readiness is acceptable from the local fire department. Are you okay with responding to 90%, 80%, 70% of calls? Normally, we'd have a military that is large enough and properly funded enough to meet 100% of our commitments, with spare capacity. But we don't have that. So either our obligations change or our willingness to meet the commitments we made changes, or some combination of those.
I would then be interested to hear what you think would be needed to achieve that number.
To begin with there's no easy fix. For example, the air force number is low because we have old fighters. And there's no point investing in the fighter fleet when we're only a few years away from starting a complete replacement of the fleet. So these have to be complex multi-year solutions where various kit gets replaced. I think getting to somewhere around 80% of readiness while not substantially growing the military, would probably require us to consistently spend around 1.6% of GDP. That would be about $4B per year at today's GDP. That wouldn't meet that topline NATO commitment. But it would prevent the kind of rust out and skill fade that we're seeing.
One thing I hate is when the Federal Government commits aid money abroad without first solving our own domestic issues. It's nice that they want to help Ukraine or fight diseases in Africa but we need to better equip our military and show we can play with the big boys.
You do realize that Ukraine aid counts towards meeting NATO spending obligations right? Also, you do realize that suggesting that we're missing out by sending aid to Ukraine is literally a Russian propaganda talking point.
Next, aid is a tool. It's one we use to buy influence. For example, CIDA will show up and do some development work that then helps a big Canadian mining company or engineering company win a large project competition there. Trudeau has been a bit of a boy scout with developmental aid. I expect the next government to kinda return to a more transactional approach. To that end, we could also return to basically spending more of the aid budget in Canada. So maybe AECON gets a contract to build railway in Senegal. They get a railway. We get basing rights in a French speaking country. Etc.
This is one good thing about Trump potentially reoccupying the White House in November. He is likely to tell Canada to go fly a kite if we do not increase our military spending and rightfully so.
I will never understand the strange idea that Trump is some genius seeking a rebalance of the deal for Americans. He literally took out a full page ad in the New York Times in the 80s complaining about the US providing security to Japan and Saudi Arabia. He does not understand history or geopolitics. It's entirely about him. And as an isolationist with nothing to stop him this around, he's going to be going all out on isolationism. Really doesn't matter which country is on the receiving end. Maybe he will relish it more with Canada, since he detests Trudeau.
All that said, Canadians vastly overestimate how much Americans think about us. I learned this during my time on exchange. They do not think about Canada. At all. So they most certainly aren't sitting there scheming about how to get us to spend more on defence. To the extent that some care about how much we (along with Europe spend), it's at least motivated by a desire to have more of that spending in the US (where the defence industry is a major employer). And this is where we are bound to have some major challenges. Not only do we spend less. But a lot of what we spend is either negotiated with substantial offsets (company winning the contract pledges to spend equivalent value in Canada) or we spend the money at home (see shipbuilding). It may not just be enough to spend more. We may have to actually start spending more in the US. And that will be an interesting new problem, if it happens. It may be the only way to keep Congress in favour, while Trump keeps pushing isolationist policies that may hurt us.
EDIT: I also would not put it past Trump to rip up NORAD, CUSMA and possible leave NATO. We need to prepare ourselves for that contingency.
Canadians are a rather ridiculously spoiled lot. And most don't have any clue how much we are dependent on the US and how much we take that relationship for granted. Even COVID doesn't really seem to have given enough of a cautionary education. I think we really should start talking about how we would deal with an isolationist US. Or even possibly an aggressive US. For example, what if they decided they are going to simply sail icebreakers through the Northwest passage. What if they start simply ignoring treaties like the Great Lakes Water Quality Agreement. Them ripping up NORAD and leaving NATO are actually not the most pessimistic scenarios I can imagine.
What I do find interesting from the article I posted is that Canadians do seem to have some awareness that we may to carry more of our fair share:
That same survey found support for Canada meeting NATO's military spending benchmark for member countries — two per cent of the gross domestic product — stands at 53 per cent. Support for hitting the two per cent goal jumps to 65 per cent when poll respondents are asked about the prospect of a second Donald Trump presidency in the U.S.
I do fear that this will come way too late to make Trump change his mind about Canada. I suspect this is why the government has held off publishing the Defence Strategy. They might want to wait to see who wins in November. If Trump, it will be necessary to buy billions in new kit from the US and start targeting Congressmen and Senators in places that kit is made to have them push Canada's case. Anand did a tour of Congress and several American states after they announced the F-35 and P-8 purchases.
Sadly, I feel like a Biden win might lul Canadians into a sense of complacency, not recognizing that Trump is not the end of this trend. Americans are clearly souring on globalism and feel like they are being taken advantage of. Regardless of who is in the White House, in the long term we should expect policy to reflect this. Ignoring this broader trend would be a mistake.
