A big issue during WWII is that the submarines were trying to find and approach the ships in order to sink them - and the ships in turn were looking out for the submarines. The submarine is forced to be close to ships equipped with radar.

Ballistic missile submarines are a completely different story. They aren't chasing anyone. Their entire goal is to be unpredictable and stay hidden, so if there's anyone with a radar around they are just going to keep quiet and move somewhere else.

Finding a sub prowling a shipping route is quite doable. Finding a sub in the middle of the Pacific Ocean? Not a chance.

I must admit, I agree with nearly all you said. Problem is that Ukraine was weak, and nearly without navy, and civilian ships was unable to resist to Russian navy. And Ukrainian export was blocked, as civilian ships fear to run within range of fire of Russian navy.

When Ukraine got enough weapons to force Russian ships to stay at distance, situation changed dramatically, so export was unblocked.

I think, very similar things happen during WWII.

This is not about only submarines, this is about superiority.
