While I understand non-violent, sometimes violence is the worst of your bad choices. I have no plan on shooting another human, but I need to reserve that right because there are people who will shoot me (Russia if you are in Ukraine)
I plan to keep out of war. However those live in Ukraine a week ago you have no choice in the matter - I cannot ignore the possibility that the same might happen to me (though it does seem like a remote chance)
Yep, we are all (in certaim age groups and qualification levels) one general mobilization away from being meat for the meat grinder. The basic "this dangerous end of rifle, point at enemy, pull there" training will be provided in those cases so.
