You can believe this is all bluff if you want, I don't. Any nation faced with annihilation has nothing left to lose, and would most certainly use whatever means it has available to inflict maximum damage on the aggressor. Russia considers Crimea essential to its defense, and will not give it up.
Russia is governed by a ruthless dictator who want to restore the USSR.
No, he wants to blow up the entire world with nuclear weapons and plans to do so within the next month, did you not watch the video?
@Archeus_Lore He’s crazy but I don’t think he’s that crazy.
