Because putin is a product of russian society every strike on Ukraine needs participation hundreds of russians. When putin dies, russia will still stay the same and pose danger.29 Aug 2026 20:19 +0000at://did:plc:usngsdkkph33lb4iplwfallv/app.bsky.feed.post/3muap73nca22jhttps://bsky.app/profile/andriitarieiev.bsky.social/post/3muaixwlpcc2uRecently discovered that Nature and Science have hard limits for free access to their news, opinions & sci-pop materials, and honestly it rubbed me the wrong way.
