Russia has long been a paranoid land power. It’s huge, mostly flat, and wide open to invasion. Just to name a few examples, it was invaded by the Mongols in the 13thcentury, Napoleon in the 19th, Nazi Germany in the 20th, and has been recently squeezed by NATO expansion in the former Soviet bloc. These events seared themselves into the Russian psyche. They breathe better with buffer states.
Whether we and the Ukrainians like it or not, Ukraine is still a buffer state within Moscow’s sphere of influence. The US has little more leverage there than Russia has in Canada. And since ethnic Russians outnumber ethnic Ukrainians in the Crimea by more than two-to-one, a Russian invasion of that part of the country is a bit like a French invasion of Quebec—troublesome indeed, and infuriating to the capital, but different from, say, a North Korean invasion of Quebec. That’s why Russia could take it without firing a shot and why nobody shot at the Russians.
Plenty of Crimeans are unhappy about it, of course. A fourth are ethnic Ukrainians, an eighth are Tatars, and one would have to be a truly obnoxious determinist to suggest every Russian on the peninsula is thrilled being occupied by a foreign army just because they speak the same language.
Ukrainians elsewhere in the country (especially outside the ethnically Russian east) are mobilizing for war.
The fact that Crimea has a large Russian population and is pro-Russian politically is no excuse for Putin to lop it off Ukraine. If the reason why is not obvious, ask yourself how you’d feel if the Mexican government seized San Antonio, Texas, and said, hey, it has a Hispanic majority, so it’s ours now. Or if the United States conquered and annexed Toronto and said, hey, we’re all English-speaking North Americans here with a common ancestry, so what’s the big deal?
That’s basically what Russia is doing.
And that was Adolf Hitler’s justification for taking the German-speaking Sudetenland from Czechoslovakia in the run-up to World War II. Putin is not Hitler, but he’s pulling the same kind of stunt and expecting to get away with it for exactly the same reason. Nobody wants to blow up the world over this sort of thing.
It’s possible that Russia might take even Kiev if Putin thinks the response to seizing Crimea is sufficiently supine. I doubt it, personally, but I don’t know that he won’t. No one can know that.
He wouldn’t get much out of it, aside from a violent migraine, that he isn’t already getting by invading Crimea. Ukraine can’t fend off a full-blown Russian invasion, but it can make an invasion bloody and expensive. And what would Russians back home think? Ukrainians aren’t their enemies. There is little hatred between these two closely-related peoples.
Bullies drunk on power do reckless and unpredictable things sometimes, though, so the possibility of an all-out invasion—even if the odds are against it—can’t be ruled out.
