Russia officially annexes Crimea away from Ukraine

Russia officially annexes Crimea away from Ukraine with signature from Vladimir Putin
Russian leader finalizes annexation of peninsula from Ukraine as world waits to see if he'll go further, or try to ease tension amid tit-for-tat sanctions with West

Crimea was part of Russia from 1789 to 1954. It became part of Ukraine after 1954. So I am not surprised if the Crimeans want to go back to Russia.
