Russia’s inability to conquer any of its neighbors is irrelevant. The possibility of them even attempting is unacceptable if you share a border with Russia. Sure, maybe Putin can’t hope to depose your government, but the destruction and deaths before his failure are still a horrifying reality that’ll take years, possibly decades, to recover from.
As for why Sweden felt the need to join, despite not having a single meter of border with Russia, it’s because Finland felt the need to join. The two countries are tightly bound and do not want to end up on the opposite sides of a war. Now they’re much less likely to.
Because now it’s practically a necessity. Before that, you could easily not put a case on your phone, exercise some basic care with it and you would’ve been fine. None of my previous phones had a case on them. Not a one. Because I don’t drop them, I don’t throw them and I don’t use them for hammering in bolts or whatever. But the camera bump finally got me to put a case on my phone, because the damn thing not sitting flat on a flat surface annoyed me too much.
