In mine, dairy is a strategic industry that is coddled by government so that we can have a local source. But every country thinks that so there’s foes and allies that can supply us UHT or powder milk on a moment’s notice. And if our milk supply disappeared tomorrow, everyone over 1y could substitute with 10000000 different things for nutrition.
Cars are another. Every country props up its auto industry, so why worry about a domestic supply?
Meanwhile, there are critical components, pharma ingredients or other inputs built in 1 factory in a country we could likely end up in a big dispute with.
Just goes to show that industry protection has nothing to do with risk/dependence on that product, and everything to do with picking and choosing which industries are important voting bases.
