While I agree that would solve much of the motivation behind rewriting in rust, I don’t think it would bring many of the rust-enthusiasts over to C. For me at least, the killer feature of rust is having a modern tooling and language with proper library management, functional stuff in the language and one language standard everyone agrees upon.

I would have agreed with you if I thought such a war could have been fought conventionally, but a single nuclear missile slipping through the air defenses would be too high a cost to pay for anything outside NATO.

And how could we do that without Eastern Europe, London and Paris being turned into self illuminating parking lots?
