> I mean, no predictive power, so why not throw out all the lessons about Nazi Germany and all that? Why waste time?
I've been wondering the same. History at school is very rarely taught as a serious academic discipline — rather, its job it seems, much like the job of the English (or any other) literature, it to shape a general cultural identity in a student. I am almost sure that among professional historians there is a common belief that it is not history's job to provide people with lessons that they can apply to solve current or future problems — I seem to remember Niall Ferguson complain precisely of that attitude among the historians at Oxford, which was largely why he, as a rebellion, started the applied history project.
> Those who do not learn from history are bound to make the same mistakes, as is commonly said.
It is also commonly said (and attributed to von Bismark) that what we learn from history is that no one learns from history.
> If anything, then the dictator is missing his history classes or did not learn properly. Otherwise he might not have acted the way he does. History could have told him a thing or two about the chances of his failing invasion or what he navigated himself into.
The dictator had plenty of other historical examples to draw upon. He could have remembered how the nascent state of Ukraine, which emerged after the fragmentation of the Russian Empire, was retaken by force by the Soviet Russia – also, by the way, engaged in a winter campaign (there is an interesting novel by Mikhail Bulgakov — The White Guard — depicting those events). Or he could have remembered the recent events of 2014, when Russia effortlessly and bloodlessly took Crimea. History, as has so frequently been said, is a whore and a harlot.
> Are you serious? Like, watch a documentary or 2 about what happened in other nations, Georgia and Moldova for example, before Ukraine. Or read up on the dictator's self-declared goals and "Russian World". Compare to Nazi Germany a little and you will see the similarities. Saying, that there is no real reason to think he would not stop is ignoring so much history.
I did say in my previous comment that there are countries with which Russia might conceivably have territorial quarrels. Those are the countries of the former Soviet Union, and those are the countries that you named. I have not heard any noises from Russia that would suggest that it is coveting Germany, France, the UK, or even Poland. If you have read anything different in the dictator's self-declared goals, then I would happily be educated.
> Compare to Nazi Germany a little
I understand the appeal of that comparison; I truly do; but surely you must see that the comparison is purely rhetorical, made due to the universal hatred of — and universal familiarity with the story of — the Nazi Germany. Why not compare with the Soviet Union (which was largely feared) or with the Russian Empire (which was less so)?
