Russia is not the Ukraine period. Maybe you have Russia confused with the USSR. The Ukraine hasn't been part of the USSR since 1991.
Crimea is a large peninsula in Southern Ukraine. In the 2014 Unkranian Revolution, a large majority of Crimeans supported reunification with Russia so Russia annexed them. The Ukraine as well as most of the international community do not recognize this annexation.
You're welcome for the history lesson Big Girl. If you are going to call people pathetic, at least know what you are talking about.
