That's why such an attack is stupid and barbaric. It changes nothing about the war and just manages to waste Russian money and kill innocent people.
If Russia's best response is really just attacking Universities and parks, it means that the Ukrainian army is invisible to Russia and Russia has no ability to strike the troops.
Russia seemingly just confirmed what we all were thinking, they have no ability to beat the Ukrainian army anymore, and have decided to simply attack civilians out of frustration.

In contrast, the destruction of the Crimean bridge destroys one of two railroads that are supplying the Russian army in the south. Logistics for troop supplies are ruined.
The strategic implications are obvious, and Russia seemingly has no way to stop the Ukrainian southern counter-offensive... And now has roughly 1/2 of the military supplies moving forward.
