This bridge has been used to transfer military equipment and heavy machinery pretty much non-stop for the past seven months, so it is a valid target.
That's correct. That's the reason why a lot of civilian infrastructure in Gaza becomes a legitimate military target during Hamas-Israel confrontations.
Gaza is a concentration camp, there are no legitimate military targets there.
That’s interesting.
Can you name any other concentration camps that shoot thousands of rockets at civilian cities? ‘Cause that’s what coming out of Gaza.
Bridges are the kind of poster child for civil infrastructure that is usually targeted by belligerents in a war. The Kerch Bridge is a key part of Russian military logistics for Crimea, so it shouldn't be a surprise that it's a target.
As an obvious counter-example: a runway at a military airfield is a legitimate target even if not in active use. Same for military aircraft sitting dark in hangars at that airfield.
Define "actively used". Is an ammo depot with no one currently removing items from it actively used? What about a bridge that's used to bring in reinforcements but has no vehicles currently on it?
Once the military uses it, it becomes a target regardless of its utility to civilians.
