I can’t vouch for the author at all, but this seems like a nice detailed, technical look at the difference between the two.
TL;DR the 212CD is very good at what in biology would be called “sit and wait predation”. It’s designed to sneak into an ocean floor crevice and hang out there, possibly for for weeks until something comes by, and then attack it. The Hanwha offering, on the other hand, is less superlatively stealthy and maneuverable, but is much more flexible, allowing missile launches and likely having a much longer range.
You’re expanding on why they haven’t nuked Kiev or any other part of Ukraine. That all makes sense. I assumed that already in my argument and went for the next - they’re not using nukes and they’re engaing in a hot war mostly on Ukranian but also on Russian territory. Therefore having nukes doesn’t guarantee you won’t get a hot war on your land. You’re not addressing that bit. I’m not saying you must, I just think there’s a reasonable argument that a hot war under certain intensity on your territoty is possible even if you have nukes. Even if less likey than without having nukes. That’s not an argument against getting nukes for Canada.
To speculate a bit, because of many of the same reasons you stated for why Russia hasn’t nuked Ukraine, I don’t think Russia would have nuked Ukraine, even in a fantastical scenario where Ukraine started the war with incursion into Russia.
Agreed on the points of Canadian defence.
No guarentees in life, but it is a bold statement with no evidence that comes to mind. Can anyone name a single nuclear armed country who was invaded?
All wars since nukes have been proxy wars by great powers. Russia is exceptional, in that it invaded a weaker, non-nuke non-threat country and flubbed it so badly guerilla strikes are hapening behind its front lines and frankly, across the country. They weren’t invaded, and Ukraine poses no real threat to the USSR so there are still no examples to support your statement.
