Russia doesn't need more cold territory thoHonestly, had Ukraine taken this path it might’ve been able to pull it off. Would’ve allowed Ukraine to build up its military while not appearing threatening. But Sweden/Finland are different political realities than Ukraine which has had its own struggles with corruption for years. Let alone a Ukraine that went through the Maidan revolution which in Putin’s eyes was the West’s start of taking over Ukraine.
I think if Putin makes a move on the Baltic states then Finland/Sweden might be pushed even closer to NATO.
