When the Ukrainian navy sent a tugboat and two small gunboats on Sunday to force their way through the Kerch Strait into the Sea of Azov, it knew in advance the Russian response would be swift and merciless. After all, Kiev was entering waters claimed by Russia with military vessels without clarifying their intent. The intent, though, was clear; to raise the stakes in the militarization of the Sea of Azov. The Kerch Strait connects the Sea of Azov with the Black Sea. To reach Mariupol, a key city in the Sea of Azov very close to the dangerous dividing line between Ukraine’s army and the pro-Russian militias in Donbass, the Ukrainian navy needs to go through the Kerch. Yet since Russia retook control of Crimea via a 2014 referendum, the waters around Kerch are de facto Russian territorial waters.
