Blowing up dams--even if the dam is a military object--is a specifically enumerated war crime under the Geneva Conventions, if attacking that object would cause the release of dangerous forces (specifically: flooding) that attacks or could cause severe losses to the civilian population

It is listed in the same category as a nuclear electrical generating facility for a reason.

Attacking them is a war crime. It implicitly lacks proportionality, and explicitly violates the laws of war.

@Pwnallthethings But can it be a war crime if it's a special military operation? Surely it's not a war?
@dascandy42 The Geneva Conventions don't care whether you call it a war or not. They care that it's an armed conflict. The name of the conflict doesn't affect whether the laws of war apply.
@Pwnallthethings If only there were an independent body capable of enforcing this convention. @dascandy42

@BackFromTheDud @Pwnallthethings @dascandy42 On the same token, the nation which started this absurd war operation does not care a bit about any laws, ethics or regulations.

"Rules of war" reminds me of rules of street fighting.
