It's about borscht. Yes, the soup.
There are a lot of folks in Russia who claim that they invented borscht. But it is pretty much universally acknowledged that the Ukrainians invented it.
Now, while the Ukraine was part of the Soviet Union, Russia could artfully claim that since Ukraine was part of Russia, ipso facto, Russia invented borscht.
With the dissolution of the Soviet Union, Ukraine became a sovereign nation and re-claimed the mantle of inventor of borscht.
This just stuck in Russia's craw. Gnawing away, like a rash that wouldn't disappear.
So, the Russians finally decided to do something about it.
As we have seen, there are a lot of Russian sympathizers in Crimea and using that groundswell of support for mother Russia, Putin inserted troops into the Crimea, held a quick election and bada boom, bada bing, Russia got bigger.
But Crimea was not enough. As long as Ukraine continues to exist as a free sovereign nation, albeit with a lot of neo-nazi, right wing idiots running around, Russia could not claim the borscht invention title.
So, what was the solution? Get a mobster to pass himself off as the new prime minister of Crimea, call for inclusion into the Russian federation and bring in Russian troops.
Now it's just a matter of time before Russia makes a grab for the rest of the country. Once Ukraine is back in the fold, Russia can justifiably say, that they invented borscht.
And that's why, it's all about the borscht.
