Actually, I am 35 not 65.
My cousins who are in their late teens and early 20s can't be bothered to get off the couch let alone fight an actual war.
I also know more than a few former international students who have no allegiance to Canada other than their PR status. If war broke out, they would be fleeing back to their homeland in an instant.
If you have not noticed, your cousins’ survival is not in the balance here, so I’m not sure how you think this is some kind of gotcha. People react differently when living their day to day lives than when their lives or country or city or way of life is under attack.
Furthermore, I'm disturbed at how you think that willingness to fight a war is inherently a positive character trait. If you ask any Ukrainian you can think of, I'm sure their feelings are that it would be best if the bloodshed stopped immediately if not sooner, they're not celebrating that they get a chance to show how much they're not pansies. They fight because they have no other option, that is all. Is it, in your eyes, a positive trait for a Russian (or anyone else) to join the fight on the side of Russia?
Get a grip.
