We certainly want to have our own capacity to be independent of other nations, including the United States. What's most important is that the supply chains be implemented among like-minded countries that respect the rules and the spirit of the WTO and the international rules-based order. They will not arbitrarily cancel contracts when there's a political dispute, or try to menace Canada if we started to crack down on Chinese state espionage or the harassment of people in Canada on some sort of flimsy pretext, and not allow us to get things that we desperately need because China's the only viable source for those components.
We should tighten up with our allies and be conscious that we need to have reliable supply chains that will not be subject to disruption and interference from countries that have geostrategic and political reasons for doing that.
