After months of tensions in Europe and international diplomacy, this week saw the start of a major international crisis. Troops from Russia have invaded neighboring Ukraine. The two countries, which were once part of the larger Soviet Union during the Cold War, have had tensions for years. Russian President Vladimir Putin, who was a spy in the notorious KGB during the Soviet era, has led Russia for 22 years. During this time, he has consistently tried to restore power that was lost when the Soviet Union broke apart in the early 1990s. In 2014, Russia invaded and annexed Crimea, a Ukrainian peninsula with important access to the sea. Russia has also been supporting and sending troops to back militant separatists in eastern Ukraine. Now, Russia appears to be outright taking control of parts of Ukraine and possibly the entire country. While this is all very dramatic and important for the people of Ukraine, it may not be immediately obvious how this impacts the United States and other countries, or how Black people, in particular, are affected by this crisis. Here are five reasons why we should care about the situation.
