Pro-Ukraine narrative:

• The sea drone attacks are not only logical and legal but necessary to offset Russia's aggression. Either the targets in Crimea will reduce Russia's fighting capacity or enable future offensives that can bring this awful war to a conclusion.

Pro-Russia narrative:

• The US shouldn't back Ukrainian strikes against Crimea as it will entail immediate retaliatory strikes. Russian warships will continue to repel and destroy Ukraine's sea drones as they are nothing short of terrorist attacks, as the peninsula is legally part of the Russian Federation.
