There are some protectionist-like tendencies in europe and that’s fine. Both laws trying to push for as much local parts as possible and buying agencies preference for local providers by tweaking purchasing terms here and there.
There’s no local industry to protect if you ain’t self-sufficiency. And it’s damn hard to protect self-sufficiency long term without protectionism if possible at all.
protectionism is an optional downstream branch of self-sufficiency - being self-sufficient does not automatically imply that it will devolve into protectionism
