My partner is not from Germany and we are considering leaving the EU for now to sit this one out. At least go to a country where you can drive away and look for shelter in case of a radioactive blast.
It's difficult, since the few who forsee things stay alive, but if you actually prepare and nothing happens, you look dumb as fuck. I don't know what to do. If you don't have family and the means, look for a smaller EU island or maybe even the US or Canada for 6 months and work from there. At least there, you can find natural resources and water to survive.
Keep the MOEX tab open and see how hard Russia is getting hit in a few hours or all next week: https://tradingeconomics.com/russia/stock-market
With these sanctions, Putin might actually have nothing left but send a warning shot. He can't go back to his country, trying and maybe failed to invade a neighbour, just to return empty handed and with the stock market close to 0, inflation and the Rubel basically worthless.
EDIT: I think this goes into the wrong direction: https://www.euronews.com/2022/02/27/ukraine-is-one-of-us-and...
So Putin is so angry and feels threatend that he wants to overthrough Ukraine, and the answer is to make them a member of the EU? This screams like more aggressives answers from Putin. I personally expect a smaller nuclear warning shot over the ocean from Putin next week.
