"Crimea Isn't the End of Russia's Black Sea Ambitions[.]" Well, sure.
Crimea is a power projection platform to project Russian military power around the Black Sea and into the Aegean Sea and eastern Mediterranean Sea to exploit Russian bases in Syria.
But yeah, NATO should definitely work to resist Russian ambitions made possible by their aggression against Ukraine. No argument there.
And one way to help resist the Russians is to encourage Ukraine to build long-range ballistic missiles capable of striking military targets in Crimea.
And we should have such missiles too, in southeast NATO, as well as minelaying capabilities to shut down Sevastopol in time of war.
