Russia, like the US/Canada, China, India, Australia and Brazil, maybe some others, have enough natural resources, manufacturing and skills that they could on-shore the great majority of things. Granted, probably none would have a best in class of much, but they could still be pretty independent. China has some mineral dependencies and India, Russia and Brazil might have some semiconductor dependencies, but they could come up with 1990 to 2000s versions of most semiconductors --and that's probably good enough. Japan, Britain, France, Germany, etc. probably either don't have enough consumer manufacturing or natural resources to survive independently.
