As someone born in Crimea and moved to Kyiv in 2014, I can tell you that a preventive strike is the last thing people in Ukraine really want now. And that is exactly what Russia wants to provoke or stage if that fails. And I will have to decide (if l will have the time for that choice) if I am going to fight or run. The former is more "right" , but the latter might be more "practical". Just appreciate the fact that most of HN audience do not have to make that kind of choice.
