There are EMP shielding techniques for solid state systems. The reality is the Soviets were very behind technologically in many areas compared to the west. A good example is the bulbous nature of their spacecraft. They simply didn't have the metalworking to make square cutouts and square windows that didn't eventually fail, so everything was round like a boat or a submarine design. Its fairly ahistoric to pretend this was all part of some master plan. It was just the best they could do and playing up the old technology as being magically superior is pretty silly. The other story you hear is how the Soviets used pencils in space while NASA use spacepens. Pencils break off graphite which could get into controls and pressurized ink cartridges in spacepens are cheap and easy to manufacture. There's no downside to using a spacepen, but lots to using pencils. Meanwhile, the few live confrontations between US fighters and Soviet made MiGs resulted in dead MiG pilots. Its clear that the higher tech and more innovative approach was superior and continues to be today. US missile defense systems keeping Russian and North Korean aggression from expanding for example.
