[Star Wars] why do they keep building super weapons? Have any of them ever been tactically or strategically worth it?

The Death Star might seem like some overly-grandoise design scheme. And it is. But that's the point.

The Death Star isn't designed to be used, it's designed to exist. It's a living, breathing symbol of the industrial might of the Empire.

Consider the modern equivalent of the Death Star: Nuclear Weaponry. Only two nuclear weapons have ever been used in a tactical environment, yet the past ~100 years of geopolitics has occurred around nuclear weapons.
