summary: After Former President Viktor Yanukovych was ousted, conflict occurred between Russia and Ukraine and the annexation of the Crimean peninsula by Russia happened. Russian tanks, artillery and air defense systems have poured into Ukraine, leaving tattered cities and more than 4300 people dead. This has lead to countries like US and Europe having sanctions which has caused problems in the economy of Russia. Russia has officially declared Crimea as part of Russia but it is not being recognized by many members of UN. Crimea has no signs of being returned to Ukraine.
Opinion: In my opinion, Russia is the one at fault in this situation. Crimea originally belonged to Ukraine and Ukraine has the right to govern the country. The vote to determine whether Crimea becomes part of Russia was very unfair as it was not monitored internationally and in the country there were already military occupation, creating fear in people. Russia should give Crimea back to Ukraine and stop being involved in conflicts with other countries. Russia has already broken diplomatic ties with Ukraine and regions like US and Europe. The only way to get back the diplomatic ties is to agree and give Crimea back to Ukraine.
