Russia is interested in Crimea because it really is a....'warm water port'....Russia is frozen each winter by solid ice. They can't get their ships out unless they have a 'warm water' that is 'unfrozen' winter port to their south. They work 'ice breaker ships' up in the arctic and north Europe but in a heavy winter they can't count on this because the ships may not fight through.
Russia already has another warm water port in Sochi (Krasnodar Krai). Also, they have rights to use another warm water port, Sukhumi (located in the Republic of Abkhazia). The issue is that both these ports are located in the Black Sea, thereby making them vulnerable to a possible Turkish naval blockade in the Strait of Bosphorus.
Russia also has a naval base in Cyprus, and another one in Syria (
https://en.wikipedia.org/wiki/Russian_naval_base_in_Tartus).
Now, let's put 2 and 2 together. What is it so important for US to destroy Syria, hm?
Those are 2 of the
very few bases that Russia has (unlike USA).
Some news from the land of absurdities, Ukraine:
Ukrainian "Crimean" prosecutor's offices started a criminal process against the director of Massandra wine factory, who allegedly opened an antique bottle of wine for Putin's and Berlusconi's visit. The bottle of Jerez de la Frontera was brought to Massandra by the founder of Massandra, Count Mihail Vorontsov from Spain in 1775 - 179 years before Crimea was illegally transferred to Ukrainian Soviet Socialist Republic.
So how come that wine is Ukrainian, when Ukraine occupied Crimea only during short 60 years, 40 of which formally as part of USSR?
