The Crimea was part of Russia until 1954. there is a very large Russian military base there. In 1992 the Ukrainian government ceded that the Crimea was almost completely autonomous of Ukraine.
How is Russia invading when it already has a massive military base there, in the Crimea, which was Russian until 1954?
Crimea is legally, according to international law and recognized by everyone but Russia, part of Ukraine. You mean Crimea was part of the RSFSR until 1954, not the Russian Federation.
Being legalistic in this circumstance ignores what Crimea means to Russia, and how the majority of Crimea is ethnically Russian. The background of the region matters for realizing how much Russia cares about Crimea, and therefore how to deal with it in this situation.
Japanese feel strongly about Kunashir too. But you don't see them sending in the military. I think thuggish behavior means you should consider their feelings less, not more. Get the military out, then talk about feelings.
It's brinksmanship of the most professional kind, there's no doubt about that. Russia can push harder than the US in this case. But of course the world needs to push back, I'm not saying take it lying down.
However, I will be surprised if Russia doesn't retain control of Crimea.

The same way the US would have been invading if it invaded the Phillipines in 1991, where it had a massive military base and which had been American up until 1946. Neither "this was our territory ~50 years ago" nor "we have a massive military base in this territory" gives a country permission to invade and occupy a territory.
