What did Russia achieve by attacking Ukraine and trying to destroy it?
Because of this attack, Sweden and Finland became new members of NATO, and Ukraine will join this alliance no later than the end of the war and will definitely direct its missiles towards Russia as its most dangerous neighbor.
Russia does not have any plans to destroy Ukraine. The goal of this military operation is demilitarization and denazification of Ukraine because it was on the brink of installing NATO bases with missiles pointed in the direction of Russia.
