Well, there's another historic precedence - Baltic Germans. Do you afraid that they maybe coming due to historic precedence too? Ask Czech Republic about them and "obliteration of culture". Do Czechs afraid of Germany coming back?
Again, I'm not trying to say that "big scary bear" is actually teddy bear. I just cannot imagine Russia being able to invade any country in EU. It's like saying there's a chance Russia would invade USA. Is it worth uranium and some bases? Doubt so. Does Russia have any resources or technical capabilities to confront EU? Doubt they ever will.
Also, about self-preservation - look at your emigration proportions [2] (shame they don't show trends - just pie charts :( ). Only this year trend is positive, but still estonians flee the country.
Good question and I would say the difference is the current regime and their actions.
Germans have been very cautious after WW2. They haven't been acting aggressively, they haven't been holding parades to celebrate Nazis as heroes, they don't have statues of Hitler in the middle of their cities.
Meanwhile Russia still celebrates everything Soviet as the biggest heroes that have ever lived, and have an amazing number of Stalin statues/paintings everywhere. Then they fund & organize attacks on Georgia [1], and annex Crimea [2]. Then, as recently as 2014, the FSB came into Estonia and abducted one of our intelligence agents. [3] This agent was denied contact with anyone, and was given premission to only use a Russian appointed lawyer. In a charade of a trial he was quickly sentenced to 15 years in prison. He was later exchanged for a FSB agent who was sitting in our prison. [4]
So you see, it's not only about precedence, but it's also about the continuation of the theme and actual real events that keep happening.
