Sixty Years On, We Still Dream of the Arrow (2021)

Doing that is more expensive and means we get us less for more - and we'd almost still rely on other countries for components and resources. All being equal, it is better to buy foreign goods cheaper and then have money leftover to focus on investing what you're good at. Canada is too small to economically fully design and build a modern plane, engines, missiles, radar, etc to compete with the US, China, etc. We certainly can't afford to do that with everything else, as well.

There are absolutely overriding strategic and security reasons you may want to do some of this anyways, but as a general rule we'd be far better diversifying our defence alliances (eg buying a mix from France, Korea, Japan, US, UK, etc) plus having something really good to offer said allies so we can be interdependent. Countries (including the US as we're learning) are not more powerful when they go it alone.

Protected industries almost always get lazy and noncompetitive. Canada is building our own version of the Type 26 frigate for almost double the cost per boat of Australia and the UK (which already ate the design costs!) despite the fact that we're going to be building the most of them so we should in theory scale cheaper. There are some reasons for that (they will be the most capable type 26's afloat), but it's mostly just because the government wants to subsidize Irving and east coast shipbuilders and there's no real scale or expertise because they literally can't market their work outside of Canada.

Russia's exports have more cratered because they're focusing on domestic demand, but they still have a market for developing countries fighting amungst themselves that the west won't supply. The one exception is India, which will likely pivot to more western kit as they have border issues with China.

Korea already had a domestic industry for various strategic reasons with North Korea being next door (if a global war became hot, they could be cut off from artillery ammunition sources, so it makes sense for them to make sure they can manufacture their own, even if its more expensive), so they're in a position to capitalize. Canada's reasons to do the same (massive arctic defence) doesn't have much of an export market, though we are teaming up with the Scandinavian countries for icebreakers.

Seriously though, those are decent paying jobs that glue together a manufacturing economy that often times is barely holding on in the face of the same kinds of forces that have decimated American manufacturing, too.

It's the same with the autosector here in Ontario.

It's not that it's "American dollars" holding Canada together, per se, it's that this is a continental-wide trading system developed by ruling classes in both countries since the 80s and it barely serves the interest of working people here or in the United States because the bulk of work has been exported to China in the the last few decades... and so what is remaining is absolutely critical to hold onto.

These are the facts Trudeau was trying to explain to Trump, who is too stupid and arrogant to grasp.

In the end working people in both countries have more in common than not. And face threats from overseas as well as our own political classes. (And no, that's not a call for the dissolution of our sovereignty.) As much as I despise my premier Doug Ford (he's a corrupt buffoon) he was right to emphasize a "fortress North America" alternative approach to Trump -- continent wide security and prosperity insured by cooperation. That line worked with Obama and Biden, and IMHO strengthened both countries, but Trump is deadset on burning it all down.

The Soviet ICBM threat was not relevant until many years after the Arrow was canceled; if you knew that before I told you, then I wonder why you even brought it up? Because Diefenbaker did? Diefenbaker was an idiot. Taking his excuses at face value is extremely dumb.

BTW if you actually wargame it out with realistic scenarios (accounting for the existence of AWACS and the probability of interceptors being in the air already), cold war US Navy interceptors easily get kills on Bears before they get their shots off, and can intercept the ASMs themselves as well. What makes or breaks it is the number of missiles brought to the engagement by both sides. It is by absolutely no means a sure thing for the Soviet bombers, I have no idea where you got such a stupid idea from.
