Use your common sense. That bridge is one of the main source of transferring fuels, ammunition and weapons from Russia to Crimea and thereafter to be used to launch attacks on cities in Southern Ukraine. My 6-year old nephew in the kindergarten also knows this, so why don't you?
Bloodymir Putin is a fucking bastard chee bye kia, long kao kia and coward. His retaliatory attacks now concentrates mainly on the civilians and civilian buildings in Ukraine. If he had bombed Ukraine's ammo depots, I would probably not have any arguments on this, but not on those innocent civilians. Even the driver of the truck which bombed the Crimea bridge had survived and that destruction had only resulted in 3 civilian casualties.
