As someone who lived through 4 years of war, my advice is to get out while you still can. As incredibly difficult as it is, it will only get more difficult to leave and it is unlikely to get any easier to stay. I have absolutely no knowledge of the current situation in Ukraine, I'm merely advising based on my own personal experience.

To everyone questioning why Ukranian population haven't heeded the warnings from Biden/West and left already - I can only assume you have never been in a comparable circumstance. It is easy for me to suggest/advise people leave, but I know all too well that's easier to type on a keyboard than act on in real life.
