Some years back, Russia outsourced some of their tank parts production. Modern Russian tank transmissions were produced in Italy. Advanced electronics were made in France. Due to sanctions on Russia, these sources are no longer available to the Russian military.
This is the problem with modern manufacturing. For example, Boeing orders lots of components from countries all over the world. When I worked at Boeing, we did lots of business with Russian engineering companies. Boeing had to do that, because other countries that purchase things demand that there be some kind of economic reciprocity in order to make up for the economic loss of buying foreign products. Boeing sold its airliners to Russian companies, so it needed to establish those relationships. I even once visited the headquarters of Boeing Russia back in the 1990s. They were an excellent source of engineering expertise for us, but that mostly dried up after Putin came to power. Russia became an unreliable business partner. That is happening to a similar extent with China these days.
Russian tank manufacturers likely purchased assembly kits for components in their tanks, and those components had to be machined and tested according to Russian specifications. Those assemblies would now need to be manufactured in Russia or the contracts transferred to some other country, such as China, North Korea, India, Iran, or other country that can be part of a newly formed secure supply chain. So this war is becoming a huge economic windfall for those countries, but it isn't clear to me that they can provide supplies that Russia needs quickly enough to be of use in its invasion plans. It often takes years for new supply chains to be formed. The West is certainly feeling some economic pinches from the loss of Russian supply chains (as barbos gleefully points out from time to time), but they are in a far better position than Russia to absorb the loss.
Totally agree. The Russian invasion has really highlighted how reliant our supply chain is on peace. I think that we need to deleverage our supply chain, bring it back to American (called reshoring) or at least only have our supply chain in friendly countries. We should not be trading with any country that is at war or threatening war with a sovereign country. This includes China IMO.
Yeah, the problem with this is that it assumes that friendship between nations is a thing, and that that thing is the cause of, and not the consequence of, peace.
It further assumes that trade isn't a major cause of either peace or friendship between nations.
All of those assumptions are highly dubious.
The consequences of "We won't trade with you because you might become a future enemy" could be pretty dire, if it turns out that "We won't be your friends because you won't trade with us" is also a thing.
And as Charles de Gaulle observed, countries don't have friends, only interests.
It's in the interests of any country to avoid war with major trading partners. Not so much though with countries with whom little or no trading takes place. You can fight them with impunity, unless their armies turn out to be stronger than yours.
