You’re forgetting that Ukraine has successfully attacked the bridge twice already.
In October 2022 a bomb on a truck detonated, causing 2 spans to collapse and killing 5.
In July 2023 two sea drones targeted the bridge & killed 2 & injured 1. The two killed were a husband & wife. The injured one was their child.
The post I was responding to claimed the Ukrainians were trying to avoid civilian casualties. This clearly demonstrates that civilian casualties were involved.
